Thoughts on loniliness

What is the point of having a lot of friends if none of them are ever there to support you. I am more alone then I have ever been, and I'm tired of always being there for others when they can't do the same for me. I need to cut ties, but really there isn't any one to cut ties with as I don't have anyone. I feel like my friendships are superficial and are convient for when others need something from me. I had no support through my divorce from friends or church members who "care" about me yet never showed up for me when I needed them the most. No wonder I lost my faith and stopped attending church, stopped wearing my garments, and ultimately stopped believing. I've had far too many trials then I could handle but I've pushed my head through trying to keep my head above water, and at times barely did so. Who was there for me in my struggles??? myself and that's all I can count on to get through. I've realized I can't wait for others to come around because they won't!
