I've just lost my best friend forever. How do I stay happy?

What happened? It's okay to be sad and to grieve as long as you need to. You don't need to be happy but it helps if you don't wallow in your sadness.

I ruined my life and they left me because I was too much load to bare.

I don't want to grieve at all as I'm scared it will deepen my depression already.

As you cannot tell us what happened, I recommend you see a counselor or a therapist.

You're going to need to grieve and learn from your mistakes, it's the only way to heal and move on.

The more you resist your depression and the time you need to grieve the more you prolong and maybe worsen the pain.

I didn't handle my alcohol well and I got self destructive.

I've been grieving too long. I can't handle any more desu.

How old are you? Maybe you need to look into growing up more and what that means to you.

For example that's a negative feedback loop, the book addresses that very feeling.
