It's hard to talk about this, but I've attempted to take my own life twice because was in love.
That doesn't sound like love.
It is love, but the other person hated me.
It sounds like you need help from friends, family, and professionals if you are attempted suicide. If your love is unrequited, you need to move on and get help from others.
I don't have family nor a good set of friends. I'm not harming anyone else so who cares if I live or not ...
Most people who have survived suicide have are glad they failed. You need to get into therapy and learn to form more constructive, mutually satisfying relationships.
