Yes, I think you can self treat. Easier with help, sure, but possible. That's based on my own experience. Suicidal for a very very long time, came close, for lots of reasons including trauma, grief over loved one. I'm fine now. Never told anyone some of the things that happened or got help from psych or meds. Maybe I would've gotten to a better place sooner if I had, idk. Point being life is good now You'll get there too. Keep being proactive!
