if one doesn't speak good Spanish, I'm not sure being in El Salvador is a good long term plan for someone mentally in a major depressive condition. it's way better than actually ending your life.

There are English speaking el Salvadorans and people can learn new languages and adapt to new cultures. I personally believe starting over would be the best thing for me in a situation where I was homeless. I really feel for OP here and hope something good goes his way
