A 10 year struggle, need advice PLEASE!!!!

I've never posted to a forum for advice before, but after trying several different means of helping myself without results, I figured it might not hurt to try. So heres the basic info, I will try to keep it as simplified as possible. Im 21 years old and have been suffering with fairly severe depression for almost 10 years now. I have gone to 3 different therapists, been on about 5 different medications, and taken meditation/yoga classes, all in the hopes of curbing these overwhelming negative feelings. My father is a verbally abusive alcoholic who refuses to get any kind of help no matter what approach my mom and I take. Hes seriously delusional and mentally unstable. I moved out for a short period of time to get away from him but had to move back home after losing my job. I thought that being gone from the same house as him would help me feel a bit better, but even while I was away from him, I still felt extremely depressed, angry, and hopeless.
I have dropped out of college 3 times, but am currently enrolled again, hopefully for good until I obtain my Associates Degree. I wake up every morning and think to myself, what is the point of all of this?, how will I ever grow up and learn to function and make stuff happen if I feel this way constantly? I eat right, I exercise, I try to maintain a social life even though my dad doesnt allow me to drive anywhere but to class and back. I feel like I'm in a bad dream that I cant wake up from, like I'm supposed to be someone else. I day dream about how different I wish my life was and then feel extreme guilt since things could be a lot worse, and in reality I'm lucky to have what I do have. I think I'm a smart, logical, humorous, creative girl, and yet I'm stifled daily by this feeling of wanting to just shut down for good and not have to think any more. My brain in fried, my patience with my father has run out, and when I think about the future I can't see myself realistically being happy. I dont know what to do anymore, and I know no one here is going to have the answer that will solve all my problems, but I'm hoping that someone out there can give me something to at least grasp. I look forward to hearing what any one has to say.

Thank you all for your responses! It means a lot that you took time to offer advice and good thoughts. Itsmee, your description of your childhood and the signs you showed for ADD are striking a chord with me. Throughout school I've had little to no focus and motivation, and would even fake illness more than average just to get out of even going to class. It's been persistent and part of the reason why I've dropped in and out of college so many times already; I can't focus and that makes me feel more depressed and anxious, the classic viscous cycle. But, with how many people are diagnosed with ADD/ADHD these days, I was worried that bringing that up to my mom would be taboo in a way. Even with my father being the way he is, my mom still has a hard time excepting my depression, almost like she maybe feels I'm making excuses for not doing the best I can. Anyways, I would love to hear more from you or anyone else regarding that. Thanks!

Hey, sorry to hear you're having such a hard time...I'm 21 too and dealing with the alot of the same problems. Serious depression and anxiety for years and it's all just feeling really overwhelming at this point :/. Have you tried therapy? I'm going to group therapy right now and it's something to look forward to in a way and it helps to have the support. Hope you feel better <3

I've been thru much of what you are going through. I understand how horrible you may be feeling and unfortunately there is no " magic' pill. I really wish there was. Taking Vitamin D3 (2000IU per day) and omega 3 really helps my mood and many studies have confirmed that they help; sometimes as much as medications. And if you have the energy, exercise helps too.
Even when you can move out it may take meds. and therapy and time to control the depression....didn't happen overnight so doesn't go away overnight, unfortunately.
