I'm so confused

Hey, I was wondering if anybody could help me with how i'm feeling at the moment. I'm nearly eighteen years old, and for the last six months I've been feeling really odd for no particular reason, like sometimes I just want to cry or i'm sad or angry with no apparent stimuli for being so. I used to be a really happy person, but now i'm paranoid (eg that my boyfriend is going to go off with other people or that others are laughing at me), I feel worthless and that noone likes me, and socially I'm starting to act really strangely. When with friends, I can clam up for ages and get really tense and worried, which usually results in me clinging to my boyfriend. The more he tries to stop me from doing this, the more I cling. I also seem to avoid going out as much.
I go through periods of panicking that noone likes me, or continuously reading over what i've said and done to see if it's stuipid. I also seem to have some kind of dark haze over my emotions, as I never know how to feel anymore.
My parents split up about two years ago, and they often argue about money, and me and one constantly is trying to sway me against the other. Now my father is moving in with a woman he had an affair with and it's so jumbled up that my head just feels like theres a hoard of bees swarming around inside of it. A family death occured abut the time I started going odd, but I havent felt able to grieve for her yet...I just feel numb...
Sorry to ramble on but I'm so confused and don't know whats going on...

Wow thats a lot to have to deal with so its no wonder you are not feeling well. A lot of the symptons you desribed i can relate too. I have depression and i suffer from paranoia, anxiety, feeling worthless, islolating myself, etc.

If i have learned one thing about depression is that if left untreated it just gets worse and gets harder to reach out for help( at least it is for me).

Good luck.
