it's a terrible feeling- loneliness. I know how you feel. I'm alone too. no kids, nothing. it's difficult to move forward when there is no one next you and on top you're battling depression. is there another med you can switch to?
I stopped Zoloft too but bc the side effects , bad ones , developed within days vs. weeks.

then you're plagued by thoughts of what should have been and where will I be in the future, right? will I be alone? I hate those dwelling thoughts and feelings. it would be nice to feel nothing again.

I don't know what the solution is. I try to break down my day by trying just to get through each hour but it's tough to do that when you have the huge cloud of loneliness hanging over. I pretend. pretend like things are ok .

I'm sorry that you're going through this terrible experience
