Life has been spiraling for a few years now

So far in my life, I have to say that it hasn't been a very normal life. Sure, there have been times where I have been very grateful, such as the fact that I have always had a roof over my head, which I think is the reason I can still wake up in the morning, but as the days and months go by I'm finding it harder to wake up mostly because of where I started and where my life has gone so far. Currently I'm living with my terminally ill mother who I take care of and my drug and alcohol addicted father. Ever since high school I have been dealing with depression and social anxiety so no matter how hard i've tried to go to college, have a job, hell even just make a friend, it usually ends with me running away in a panic attack. I have been on every anti-depressant (literally, my psychiatrist once gave me a list and I was able to check off every pill on the list), and I have tried every therapy treatment out there, partial hospitalizations, day treatment programs, multiple therapists, with little to no success. I think my problem is that it's always been said of me that I'm a very self aware person which is nice to figure out what is wrong with me, but when going through treatment exercises, it's also easy for me to find the faults of each exercise as it relates to my situation so it's hard for me to just go with it.
I could rattle off all of the bad things that have happened to me since high school really and why all of this holding me back, but at this point I'm a bit sick of telling people from therapists to social workers over and over everything that happened to me so my question is, has anybody ever tried to leave it all behind and start their lives anew in some place where they no longer had to worry about leaving their bedroom because they don't want to smell cocaine burning in the next room or try to convince their mother over and over that we both need to leave this personal hell if they want to really live? I'm at a point of dreaming of packing my clothes and selling anything I can just so I could have enough gas money to live out of my car. I currently abuse my anxiety medicine and take any other over the counter medicine that makes you drowsy just so I can be numb from everything around me. After years of trying to make changes, I have resorted to this option because honestly I have no more fight left in me. It's why I want to leave so bad, I feel it would allow me to see that there is another world out there, a world worth fighting for again. Has anybody else ever fought what seemed to be an impossible situation in order to get their life back?
