I'm sorry for your loneliness. To answer your question, I certainly have wondered if people would miss me. (And even if many people would come to my funeral.) I think those questions tend to go along with depression. At least they do for me.
However, I am married, have children, other relatives, and some friends. So, I'd like to think somebody would miss me, if only to think "Well, I'm glad she's not being a pain to me any more!") Yet, I try to be a decent person and to be helpful, the best I can, so maybe there are some positive aspects about me that might be missed.
I see you have labeled yourself "Doggiedoo." I KNOW you are more valuable than that, even though we haven't gotten to know each other yet. And I see that you believe in miracles. I do, too.
Are you seeing a therapist? You do sound depressed. (I know, that's probably a dumb thing to say. After all, you posted in the depression forum.) I can tell you that there are people in the world who would like to get to know you and be your friends. It's sometimes hard to reach out, but it can be done. In the meantime, have you checked out the folks who are lonely social group here at PC?
Please keep in touch here. I already would miss you if I don't hear from you again! (And I WILL not think of you by your self-chosen name, for goodness sake!)
