I don't know who I am/don't like who I am...?!

I don't know who I am/don't like who I am...?

I'm 17...I've got no real personality...I don't know who I am exactly. I don't know what persona to have...the funny girl, quiet girl, the smart girl, the bad girl, the good girl. I don't know which one I want to go for.

I'm an introvert and have depression, it sort of handicapped me and I don't know who I am. I don't just want "to be myself" because I don't know what myself is! I have to shoot for a goal, is my goal to be funny, resourcful, confident?....right now I come off to most people as quiet, annoying, and depressed and shy. Which they're right....I have a loser personality. I don't know what to do! How do I decide who I want to be? I'm confused.Thanks for taking the time to read my endless ranting about self-finding.

Some of what you feel is normal for your age, but you don't have to limit yourself by trying to pick one "personality.
People are multi-faceted, and it is normal to feel different ways, to "be" different ways, at different times.
I think you are too depressed and confused, personally, and I would urge you to get some counseling, like cognitive behavioral therapy; eat right, and get lots of exercise- really, those things really do make a difference in how you feel about things. Also, believe it or not, looking in the mirror in the morning and repeating "I like myself, I recognize who I really am" really can make a difference. It is called affirmation, and tens of thousands- if not more- of people use it on a regular basis.
(Please don't be so hard on yourself. I went through a similar time when I was your age and I did finally pull out of it.)
