Mental health veterans, it is literally impossible to get an date, are we facing loneliness?

I am a veteran disabled by Major depressive disorder, in addition to that, a year ago my doctor diagnosed me with bipolar disorder in addition to my MDD. When I have met people, I hide that side of me, but when I tell them my conditions due to service, they literally disappear, they think I am a psychopath or something like that, my last experience was a girl who saw my medications (which are quite a few), and read their labels without me realizing it. And she asked me why I take that, I explained it to her, and it happened, I never heard from her again. Mental conditions do not make us psychopaths, mental conditions are suffered by us firsthand and only by us, why this stigma? I think that loneliness is what awaits me until the end of my days. Not only in romantic relationships, but also in friendships.
