Hi whenwillitend. I'm sorry you are going through so much pain right now. I often find I feel the loneliest when I'm in the company of others, especially if they are going through hard times themselves. People are often at their worst during these emotional periods and the situation can be so draining, it's not surprising that people lose hope the situation will change. I find I do best and can think more objectively if I get away a bit and go for a walk.
I hope you can find some breathing room to remember the good things in your life. Best wishes for you in this difficult time.
