I've been thinking about starting to date other people. I'm tired of being lonley all the time with nobody to talk to

I don't want to live in this world a lone
I'm Bisexual so I don't care if the person is either sex.
I would like to ask some of you experienced people out there that is it healthy on the relationship to date other people with similar mental illnesses that you have?
I have Bipolar, BPD and depression including anxiety and PTSD.
Should I try to avoid other people with these diagnoses? Has a relationship ever worked out when the two has almost the same illness? I don't want to create a discrimination and to continue with the mental health stigma, that is not what I attend to do.
With what I have as far as my symptoms goes.. I don't think I could handle somebody else's similar symptoms as what I have
If I were to clone myself and the clone had all of the symptoms that I have, I don't think we would handle each other, which is what I'm trying to pinpoint.
Whats your opinions of dating other people with mental illness?
