I wish you all the luck and hope I didn't belittle your situation. I am glad you had the opportunity to turn it around. I am also envious and was surely reacting partially because of that and the frustration of my own life. I have had close friends who were able to dig out of various kinds of holes and the universal truth was they had access to various options...social systems, family, were physically healthy and had the option to change environments etc. Not everyone has the same available paths to recover and I often, maybe unfairly, get frustrated with people imagining it's like that and if "that guy can do it so can you so why aren't you doing it?" and they just refuse to see the confirmation bias.
I don't think there is anything wrong with giving therapy a try if one is depressed or has other issues. My problem is people seem to focus on that and pills rather than the underlying issue...whether that be physical illness, money troubles, no support network whatever. When someone is suicidal people react with this idea the fix is psychiatric care. I disagree with that entirely for the majority of cases. If the boat has a huge hole in it you need to plug the hole before you can effectively bail and dry things out...otherwise it's a losing battle and all the positive attitude, introspection, and coping skills in the world won't keep you above water and you are just avoiding reality while drowning. Some people get through it to the end like that...I have not been able to.
I am frustrated mostly because I know I could at least live out life if the conditions were right. I will never be truly happy or have my dreams fulfilled because my physical health is permanently damaged, but I COULD realistically survive and not feel this terrible if I could only access the conditions that are just on the other side of an ideological, political wall so close I can see them. So it goes for countless people...lest I sound like it's all about me.
