Being myself is hard when I'm not sure who myself is

I know.. That's the same with me. I still have bits of me. I hang out with good people expect for for this BITCH!!

I do things that fictional characters would do...

I know, it's almost like being around people for an extended period of time has an effect on how you act in social situations.

That's everyone's personality. You take the traits you like from other people and build your own. It's not a bad thing, it's just learning behavior. Makes you a better person.

everyone is a product of their environment. this is normal

Honestly this is so true. I feel like I just talk to people, and copy the shit tout of their best qualities. Same with characters from books, and shows too.

I have a classmate that says a particular word for a lot of responses. "I almost failed the exam" (insert word here), "I finished the project yesterday, right before the deadline" (insert word here), "I broke my finger" (insert word here)
.....
...
Guess what word a couple of our group say every now and then. HIS word; funny thing is, we are aware of what we are doing, but we just don't know how to get rid of it.

I have a different personality depending on who I'm with. I kind of just judge how the people act and do what I need to fit in. I have no idea how to actually be myself, because I don't really know who I am.

Honestly same

That's sort of the point of being around people?

Stolen exactly from nine-gag and there is a watermark on the bottom right. Should be deleted.

That's how it works for everyone, personality traits don't just materialize out of thin air.

Hey, that's how most characters in books/movies/games/comics/etc are made so...
Maybe you're a higher power's main character.

Same here... Same goes with my expressions,humor,style...
WHO am I really?

The point is HOW you mix it... also, get good friends, or you'll get a bad personality.
