I was wondering what some methods are that one uses to maintain hope?

When my big tragedy happened, I made sure to take some time. I wanted to heal, and get my head right. I wanted to be a whole person, and be better should the next come. It would seem that in that process, while it took a while, I did heal. To be able to heal, it cost me my ability to socialize. I sometimes feel borderline feral. I can't seem to relate, I know not where to go to meet people. Even if I did, I'd likely be unable to engage or relate. I'd greatly appreciate one to at least chat with. I am currently at the decade mark since the tragedy, and a large amount of loss has again fallen on this one to mark the occasion. I am about empty of hope, and can no longer find reason to fight...

Any insights would be greatly appreciated?
