What is wrong with me..?!

What is wrong with me..?

i dont know if its just a depressed mood, or clinical depression, or an anxiety disorder or what.
but ive been feeling depressed for almost a year and its just gotten a lot worse over time.
i have no intrest in anything & ive stopped communicating with a lot of people, and shut them out of my life.
i feel completely worthless.. like i dont have a reason for living and no one wants me here. ive been cutting for about a year.. and ive done it a lot more in the past month, because.. i just need to feel something.
at night.. when i try to sleep.. i never can. i just think about everything, and its like i have tons of thoughts just racing through my head, and i can never fall asleep until like 2-3 hours after i try to. .. and its really messing me up.
and sometimes at like random times during the day, ill be thinking about something, and ill start crying, hyperveniliating and freaking out.
i really just want to be happy.
does anyone have an idea as to what could be wrong with me?

I too suggest seeing a therapist or psychiatrist. It sounds like you have a lots going on in your life you need to work out. Honestly a person that is not a specialist is not going to be able to help you. So first thing tomorrow morning when the offices open I would highly suggest you try to find a good therapist. Good Luck!
