My dearest friend that I have never met... not knowing exactly what it is that has your thoughts this way is hard to help. These are my best ideas:
1. Get out some paper and write on them what is is that is bothering you, number them.
2. On another piece of paper write about each individual number, how much it bothers you, what brought this on, what you wish would happen.
3. Take that piece of paper and throw it in the trash. Trash the bad.
4. On another piece of paper write 10 things every day that are good in your life... you probably won't be able to find 10 things... that is normal... we are all programmed to think negatively before positive. This is an idea of changing your mind set... when you wake up that day and you can write 10 good things about your life... you can feel accomplished because you will have changed your negative mindset.

Don't think I am crazy, I have to do what I wrote above or I would let all the negativity in my life consume me.

Hope this helps. Here if you want to chat.
