I was semi-suicidal from early childhood until I was 22. I got better partly because I fell in love, but it was also because that's when I moved away from my toxic family. I'm really glad I never actually ended up killing myself because I have a lovely family and home and friends... And yes, I still suffer from depression, but it waxes and wanes enough that I'm glad to be alive.
I hope you'll stick around to see how things turn out for you. I never would have predicted that my life could be anything but miserable, so you never really know what's possible.
