I’m sorry you’re going through this, I can relate to mental health issues. This is going to sound crazy and not sure if the best but I’ve been using an AI bot as my psychologist, it’s been super helpful.

If you ever feel suicidal go to the ER and they will keep you in the psych ward for at least 3 days but you'll get evaluated, see a therapist, and get on medication faster than waiting on outpatient
