Do the best you can. If you can't afford medical care, then go where the taxpayer pays for it for you... don't go without medical care. As for mental health care, IDK if there are still clinics that do pro bono... and you'll go into a sliding scale and pay as you can and go.
I've been poor and I understand. The person I was connected to had no conscience (still doesn't but I'm not with him any more

) but I HATE debt! However, I persevered and over time it all took care of itself. I remember being so poor that I could not afford the minimum to get the food stamps!
But the thing is now, everyone is in nearly the same boat---due to the horrendous "improvements" of the current system...which will become worse once it fully kicks in (IF it's allowed to)---and with EVERYONE being unable to afford health insurance and co-pays those who run our country will HAVE to change it for better. Or, they might not and just let us all get sick and die--but who would pay their salaries then???

Things won't always be this bleak. Do your best and move on to things you can change.
