HI Scotty
I am sorry you are having such a bad time of it. I have had pretty severe issues with my schizophrenia, but I manage to bounce back.
Most of my severe depressive moods have not been triggered by anything particular, and as you know its easy to slip into one without any warning. I guess I have never lost sight of the fact I am actually a person with a value, with a few flaws.
One of the big things for me was having someone I could talk to at length. Most of the people I know have a mental illness, which made it easy to talk to someone who sort of knew the ropes anyway. If you cant get to the GP I hope you have someone to talk to, who will listen.
I have used lifeline when I was really down and took myself off to accident and emergency if self harm was an issue. You obviously have insight into how you feel at the moment and that's the biggest issue towards getting yourself right.
If it helps you to dialogue through this thread,go for it, there are plenty of us who can and will listen and respond, endlessly if we have to so that we can give you plenty of support. As I said before, if you need immediate help ring one of the crisis hotlines or go off to the A and E.
I have used both with very positive results. If you want to talk, there are plenty of us here to help you out with conversation and advice.
Scotty, I have been through a lot of bad stuff in my life but with the support of various people I got through it. Hope this helps.
