How am I going to get through this?

I am a total failure. I quit my job last year to work overseas, i really hoped that it could work out and be a fresh start but it weren't. Now i am back in my hometown. i managed to get a job but is desperately unhappy there (plus it pays less than half what my previous job paid). My colleagues are trying to get rid of me by trying everything in their power to make life hell for me. I don't know what to do with jobs being so scarce these days. I have applied for so many jobs and a few interviews but cannot manage to get a better job. I have never excelled at anything in my life, i'm not attractive, i don't have money. Everything is a mess

Please don't take disappointments seriously. They will only pull you down and make you sad. If you think you are a failure, then you belong to the majority. The world is full of people with failures in their life. So don't lose heart. Keep dreaming regardless.
