Yes, I have felt like I just wanted to die. There a certainly such moments. There are also times that I enjoy being alone, being able to do my own thing. I also have family & friends, but sometimes it would be nice having someone sleeping next to me, and I miss that.
Doing things like being on this forum, or Facebook helps at times, but not always. Lately, I've been focusing on getting a relationship with myself. I know it sounds a little weird, but I will look at myself in the mirror, and talk to myself at times, and tell myself that I'm worthy - things like that. I've also started making plans to do things that I normally wouldn't do by myself, like going to the movies, short trips to other places, sight-seeing a little, etc. Just because I'm alone doesn't mean that my life stops. This does help.
I'm certainly not a stranger to relationships. Been married & divorced 3 times, and have had 10-fold as many girlfriends. I have two sons that are both grown, and living on their own. So I've had people in my life, and have been without anyone in my life before. I can say that being active on this forum is a plus.
