I feel utterly defeated and like there's no hope for me to ever find someone, so what's the point of going on?

I've been depressed for years now due to being lonely or due to relationships not working out, both due to the fact that I have avoidant personality disorder and social anxiety disorder. My depression does not seem respondent to treatment, which I assume is due to the fact that my depression is rooted in this loneliness and talking about it or taking medication isn't really going fix that. So yeah...I don't know what else to say, I feel like I'm way too deep down in this darkness and feel like I'm fading away.
