My advice is:

- Find what you're missing in life. A companion, a good time, etc. (Note: This isn't so easy, so I'm sorry if it comes out that way )
- Broaden your horizon. By this I mean find a new hobby, try something out of the ordinary, learn about something new!
- Be positive. There are so many great, beautiful things surrounding us! Lie down in the grass for an hour!

I hope at least one of these can help you in the destructive position at this time. Everything will work out fine
