Hi! Welcome to the forum. I'm new this week also. I can relate to your feeling lonely and hopeless. I am 34 and have only dated twice. I am very uncomfortable in social situations and atry to avoid them. A few years ago I wanted to be married and have children so much it was causing me physical pain. I felt hopeless and was discouraged because all of my friends are married.
I've really worked on trying to be happy with my situation in life. I've started going out to eat by myself and to the movies and museums by myself. It doesn't really solve the problem of loneliness when I'm home, but it makes me feel more alive and vital. At first I was uncomfortable going out by myself, but now I enjoy it. It's hard sometimes, though. Mostly I worry about growing old alone. This may sound strange, but I worry about retiring and not having enough money because I haven't been able to save and I worry about dying and no one noticing for awhile because there is no one to care about me. I'm sorry if that sounds weird, but that's me.
I also want to apologize for going on and on and on, but I love to talk.
