I used to volunteer as a listener on a mental health suport site.
Met many people there who needed support, so I helped them by listening to them and befriending them.
Not easy since I wasn't doing that great myself, but I put my issues to the side and tried being there for them all the time.
Had to be there with them on chat listening, comforting them, understanding them and helping them find some good help and letting people around them see how much they are struggling, because they never felt comfortable enough to share with others, so with my help they found a way to open up about their issues and get the right help
Saved many lives doing so.
This another thing was fucked up but I tried getting a girl I had met away from her abusive parents. Looked for a place she could rent and helped her find a job, paid for most things.
All in all it ended up fucking me, her parents accused me of kidnapping her. I don't know if I could trust her either as she wasn't doing things right at the time when it came to legality of all, she did clear up the accusations against me in the police station.
