It's not gonna be what you want to hear but you should try and build some friendships first in my opinion. Even if it's online.
It's wouldn't be healthy for either person in a relationship if you relied solely on them emotionally, and it also wouldn't be fair to either of you if the main reason you were with a future partner was because you wanted to be in a relationship as opposed to feeling a real connection with that person.
It also seems like you're seeing a romantic relationship as a kind of fix or something that would give you a reason to live, and that's setting yourself up to be disappointed because you'd still be suffering from mental illness while in a relationship. A partner could offer support but what's really going to help is changes you make to your lifestyle and outlook, hopefully with professional help to make those positive changes.
So yeah, my advice is focus on building friendships and maybe from there let a romantic relationship develop naturally, or at least build a social group as a foundation and work on your mental health 'til you're at a point where you feel like you can date

Sorry pal, you're shit outta luck. You want the reward without putting in the work. Life doesn't work like that.
You have 2 options:
A) continue as you are and be miserable.
B) Get off your ass, put in the work required to be a functional adult, and actually do something with your life.
I guarantee that no girl on the planet will want to date you if the only thing you're good for is keeping the couch warm.
