id slap myself silly if i could...

sooo today i was talking to my sister about "judging" people.
and i told her that i do too much of that. i honestly do, its a problem.
im always judging people and ive realized that ive missed out on what could of been good friendships all because of my stupid insecurities inside.
i guess it all comes back from middle school. everyone judged me on my appearance.
so it all was boiling up inside me. until it unleashed itself on innocent people. maybe they were nice maybe they were a-holes ill never know.
how will i change? can i change? im a very sensitive person that keeps there feelings inside,i guess im bitter from all the bullshit thats gone in my life.
but there is also alot of good things that have gone on too.
and i have good friends that didn't judge me and got the time to know me.
its all up to me i guess.. and my perspective on people...
i need to let go of my bad feelings. i cant keep on living this way.
