What has helped me is seeking recovery. I've tried to recover many times. I've been taking meds since I was so desperate, but they don't work.
Do the things you want to do, that are within your abilities. Try new things and focus on yourself. Have a plan and be prepared, think of this logically and not as a spur-of-the-moment thing. When I go, I will have all of my ducks in a row and I know I will be making my decision after many earnest attempts at changing my life around. But ultimately, none of them worked and most of the time doing the things that were supposed to make me feel better ended up in worse things happening. Mental illness of this severity will never go away, especially not if youve put effort into treatment and it hasnt worked. So, I will die by suicide.
I've considered it during the best of times and during the worst of times as well, and it always feels like the logical conclusion to my life.
If you are inclined towards religion or spirituality that might also help if your worries are about life (or lack thereof) after death.
