Ive been struggling with suicide thoughts and attemps for over 10 years off and on. Its no picnic for sure. I have gotten treatment from a psychiatrist and am on medications. The meds seem to help but I still get down on life at times. I seem to be in a pretty good place right now. Yes loneliness can be a real sucker punch to the spirit. Your not alone in your situation. All I can say is that things can get better with some help and some effort. I manage to have a lot of good days and have a lot of fun with friends and family. For me the best thing has been for me to have learnt some coping skills. and also keeping on my agenda things that I like to do. You got to have something to live for. I hope things get better for you.
