I'm ashamed of all my somethings

so
apparently some of my friends had a discussion
and came to an agreement that I will most likely drop out of college
because i have no goals
and i don't push myself

which is true
I coasted through high school
but from what I've heard college is different
and I think I'll be able to adjust to it and it will work for me
me failing at college is one of my biggest fears
and to have it thrown in my face is kind of scary
like I'm not the only one that suspects it
I don't have the best self esteem so I don't expect much from myself
but to see that other people don't either
scares me

Maybe I was right all along
maybe I really am nothing
maybe no matter what I will fail
maybe everything I think about myself is true

I used to believe it all
until I "got help"
Now I don't know what to believe most of the time

I guess I'm just confused.
