I've never been able to figure that out either ):
That's mostly why I keep myself busy nearly 24/7.
It's like a mini depression episode for me- sometimes I even cry about it when it's just stupid stuff.
But like I said, I dunno. :b

Ohmy Quad that same thing happens to me.

I'll be minding my own business, and a memory from when I was practically five will appear, and I'll feel guilt creep up on me for it, even though it's long said and done- or maybe I didn't do something, and I feel regret for having not done it.
Guh, memories >|

I'd help you, if I knew how to stop it myself.

Try vent writing, then? It might make you feel better. ^^
And also, if you didn't mean to say that, there's no point in blaming yourself. Even if you did, it's in the past now. I'm sure anybody who's involved has totally forgiven you.

I know; it really is hard to forgive yourself. You're your own worst critic, right?
If you have low self-esteem, maybe that's helping to let you not forgive yourself?

This happens to me. I thought I was the only one. ._.
It's weird because they just pop up randomly. I know chances are no one remembers these things, but then I wonder why I remember them. Sometimes it's something from when I was little. Usually, though, I might feel embarrassed for a second, but then I tell myself that most likely no one else remembers it, and that it was a long time ago and doesn't matter anymore anyway. And then it will go away. Usually. But then sometimes they persist, like they keep coming back at random times. I just have to keep telling myself, that no one remembers, or if they do, they probably don't care. I know that if I were to bring it up with...whoever was with me at the time...they probably wouldn't know what I was talking about.
Well all I can think of is try to ignore them and move on. Just concentrate on whatever you're doing.

Glad I'm not the only one this happens to. ^^;
My mind also does another thing: it will come up with the worst thing that could happen without my control. Anything I'm about to do, it goes pessimistic on me.

Thanks for the suggestions, everyone. I vent-wrote a story which I think helped. Also put Quad in the Forest and let him listen to the sounds.

Thanks for the company, Ocean. I'm going to log Quad off now, but he just needed to sit with someone. Sorry if I interrupted anything you were doing.

I know that feeling.. i remember all this stiuped stuff thatt i did.. and they just can come really randomly..
I mean im sitting at class and then i start thinking and somehow im getting this memory and i'm all like:
"WTH.. why did i do it!? i mean for what good reason?!" D :
But after im asking myself why i did it.. i start to say to myself ,that it was the past.. no one remembers ,so why should i remember and be ashamed. >w<
You should understand that it was a stiuped thing (as you say) and just let it go ,to say to yourself "Yeah ,it was ,it was embarrassing ,but no one really remember it ,and that was the past..so it's okey"
Or something ^^

At least I'm not the only one who does it.

Alright, I'm gonna tell myself just not to worry about it whenever I think about those memories. I think that's the unanimous suggestion and so I'll give it a shot. Thanks again everyone.

Mhh... I wish I had the ability to forget, too.
I remember way too much.

Whenever a very unwanted thought comes up in me, I try to focus on something else immediately. Usually I try to play a complicated game in the internet or on my iPhone, or I try to sing a song which's songtext I used to know, or I try to phrase some sentences in French and Spanish,... Something difficult that requires my full attention, so my thoughts can't fade away to bad memories. :B
It does not always work, but sometimes it's helpful.

Huh, I think pretty much everyone has those little memory punches. It's like they're forever connected to invisible strings in the back of your head. x.X.

(doesn't matter much I guess but...) I suggest writing about them, tearing it up, going for a walk and dropping the bits in the waste bins you pass along the way. I like to think that every bit is a bit of the problem... then go home and just be aware of things (the tiny things like the noise of my own feet on the floor or the barking of the neighbors dog or the sound of cars or birds or wind or the hum of the fridge...etc...

I second Tenley too.

Uuuugh I go through that all the time. I wish I knew of a cure too ._.;

Here's my theory:

It's been done. Worrying and wondering why you did it, is not going to change that, so what's the point of spending your life worrying. Just let it all go. You can't change it now.

I don't know whether this will help or not, but no one has mentioned it yet so I thouhgt I'd let you know that there is a very valid reason for why we can't un-remember traumatic or life-threatening events from our lives. It also is the reason people suffer from PTSD, and why crazy events in your life might seem to play back in slow-motion in your memory.

When your body starts sending signals to your brain that something VERY BAD is happening (trauma, injury, etc...) the brain triggers a series of neurochemicals to activate a part of the brain called the amygdala, which is responsible for coding long-term memories into your brain. The amygdala initiates the recording of extra memories so, if you survive, you’ll be more likely to avoid the situation in the future.

Your brain is arming you to avoid danger by keeping a record of all the stimuli associated with a harrowing moment. When you compare your memories for the event with those immediately beofre and after, you have more information than you do for the events before and after the scary time. Also, your subconscious is endlessly attempting to dredge the memory up and reanalyze it for every possible useful detail, which you manifests as obsession with either the memory of the event or behavior associated with it. This is particularly true in childhood, when the amygdala is far more robust and active. Everything is new, so you record more memories than you do in adulthood when everything becomes routine and common. This is why an awesome summer's afternoon from your early childhood can seem like it lasted a month.

Science.
