My fiance has depression, anxiety and psychosis. I love him with all my heart.

Being depressed and anxious does not make you unloveable. But I will say it's probably unlikely you'll find your true love online through your blog. But then, is that what you are after? Probably not. So don't worry if readers sometimes don't respond the way you want, they aren't the people you are wanting to share your real life with so it doesn't matter if some of them don't love you.
