Sorry that this happened to you! Getting over someone leaving you is bad enough, but knowing that it was because of your illness might make it even worse. Maybe as a result of my own experiences, I am today glad to be single, and seeing all the benefits of that.(no more drama!) I think the best thing to do is to focus on making a good life for yourself no matter if there is a partner by your side or not. I find that spending my energy on nurturing good friendships and growing as a human being, is in the long run more rewarding than being sad about the fact that I am single. I hope this does not come across as preaching... just wanted to offer another perspective. Sometimes life gives us these horrible punches though, and it can be real hard to get up. But with experience and learning and growing, we will also have a lot more to offer a potentional partner. And the difficult experiences might make us better at judging who is worth spending our time with, and who is only going to hurt us.
