(TRIGGER WARNING) please help

Okay sooo I’ve had a pretty bad life, and lately my self esteems gone way down and I feel like everything’s my fault, I can’t do any good, and that no body likes me. I haven’t done self harm but lately I’ve been thinking more and more it’s just easier not to live. Like i know people care about me but it feels like i have no one to talk to and no one would care. I also wanna talk to this one person about it but how to I tell them I want to talk to them without sounding weird or needy?
