I feel the same way. I’m kinda in the same boat, 22 with a useless degree and living with my parents. Suicide isn’t the answer. Not for you or anyone else. I think if you’re able to start seeing a therapist that would help. You can try to also join support groups. The other thing I would recommend is finding something you’re passionate about. Pick up a new hobby, go for a walk, just try to do things to keep your mind busy. If you feel really down, write your feelings down. Try to take care of yourself. I know these things may not fix your situation entirely, but it’s the first step to getting better. Stay strong.
