Can my brain hide bad memories or feelings from me

Sometimes I get really upset, but I don't know what it is.
I forget important things/lose value expensive things.
For example( MY homework, iphone 5, certificate award paper, expensive ring and earrings, 2 tennis rackets, tennis uniform) i lost all this stuff this MONTH.
In class, I daydream 1/3 of the time.
I'm insecure.sometimes.
I have problem forgiving people. It's almost impossible for me to forgive people.
I always find myself the victim.
I always think something is wrong with me mentally.
QUESTION #2) what is wrong with me?

I do the same thing!

I think your brain can hide feelings from you because i never get sad no matter what happens i think all the feelings are just bottled up in a deep dark place in the back of my brain

If you are able to repeat without any mistake, utter: BAD BLOOD; GOOD BLOOD, repeat it one dozen time. If you don't commit any mistake in its pronunciation, you are considered an Expert.

Whatever you think deeply and conceive in your mind with ardent devotion, that you can surely achieve.

No your brain can't hide bad memories from you because our brain is complex that's why we're smart. So bad memories are special data stored in our brain that are hard to forget. But over time you will get over it. You day dream as you get over bored. And you forgetting things is a sign of your brain having problems.go see a psycologist

No clue

Heavy stuff. I forgot my trainers when I went to the county athletic chamionships. Had to run the relay in my bare feet! The rest of the team were not happy!

I daydreamed at least 2/3 of the time when I was young, so you're short. I think that you are simply a normal, intelligent, imaginative teenager. You could write things down, but you'd probably forget the note.

I play golf now, badly. But I forget all the bad shots and only remember the good ones so I keep going back. Yes. The brain does sort through the memories and discard the ones it doesn't like.

ps I'm 59 and I still daydream!

A quick scan of the literature reveals that the scientific assessment of remembering bad/good memories is unclear.

You are probably depressed, too much work? Studying? Miserable childhood? Poor love life? Being bullied? Have any friends? Family hates you? Eating disorders? Anyway, put yourself together and if you can't doing by yourself, seek professional help, before doing something stupid and making things worst and hey, don't play the victim part, you ll end up annoying everyone around you and your life will be even more miserable than you think it is right now.
