Hi,
I feel your pain. I do not believe in fate although some of us are born with (or acquire) certain conditions that make difficult for us to keep relationships for several reasons including stigma. Perhaps we should try to concentrate on those things we can improve not only in ourselves but also in society. At the end of the day, it is the only thing we can do.
Clearly, we have understood that life is not fair. We are far from the model of happiness advertised on TV or that we imagine other people enjoy.
But that does not mean we will not be able to encounter a soul mate, ever. When we hear a voice inside telling us "you will never find love" that is not true. It is depression speaking, I am sure
