how do you cope living by yourself with little support network

this is me, i'm well into my 40s now, had a hard past & never managed to find any relationships, i have a personality disorder....and i have basically ended up alone in an apartment by myself, with my only support structure my elderly parents, mainly my mother who lives far away.

i get lonely, isolated, disheartened, discouraged and miserable...i was always quiet, shy, introverted but i did hope to build some relationships, find a nice lady, but that never happened.

anyone out there similar? how do you deal with it?
