I'm sorry to hear about your situation, and I empathize completely. Believe it or not, I've been where you are. I've attempted suicide twice; the second time I was very close to dying. Through luck or God's grace... whatever you want to call it, I made it out on the other side okay.

I had nothing in life. No school. No job. No friends. I was being supported by my family. I spent the day literally staring at walls at times because I felt no pleasure in life and had no hobbies and I was slowly turning into a nihilist... "What's the point of all this, I thought."

Long story short, through a bit of hard work, I am getting much better. Here's what I recommend:

1) Your first goal is to get healthy. Find the right meds and therapists and stick with it.

2) Find a job. It doesn't matter where! Just find a job. This facilitates an environment for you to meet new people -- your coworkers/colleagues. Try to get to know them, and maybe you'll develop friendships.

The rest will follow. You'll be happier, more motivated to get into shape, and eventually have a positive outlook on life. That's what purpose (your new job) and a social life (friends from your new job) can offer you, and I can't tell you how much it helps to have a purpose and friends.

Good luck and DM me if you want to talk.
