I am feeling hopeless about dating because of my diagnosis

I am feeling hopeless about dating because of my diagnosis. It's already difficult because of my age(I am 45), but the last 2 times I disclosed my diagnosis, they expressed disinterest. I hope to meet someone one day that would be open to having a long term committed relationship.

We wanted to check in with you and see how you were doing and how we can best support you.
