I am sorry you are unable to overcome serious issues. However you may wish to discuss your feelings with a professional as your apparent solution may not be the only one open to you.
I am sorry to hear of your troubles. I recognize that life changes can seem insurmountable. They are not. Please don't let your immediate feelings outweigh your long term outlook. Things can and will get better with time. It just may not seem like it today. F. Sharp's suggestion is a good one. Seeing a professional may help.
