I really really believe you need some serious professional help. I urge you to seek it.
My job was a place of refuge going through my divorce. I was very close to my coworkers and I was an ICU nurse. Helping others less fortunate put a lot in perspective for me.
Volunteering and community service also helps. I feel so good helping other, I count my blessings, and give back.
What you are doing isn’t working. Clearly. So what are you going to do differently? What is one tiny little step you can make to improve your mentality?
