Ask HN: I hate working alone, but I want to pursue my startup

My concept is decent - I've received pre-seed funding from the EU off the back of it, but it now needs full-time attention to get the first customer, probably for the next six months. I'm prepared to quit my well-paying job to pursue it. I have about 2 years living expenses saved up.

But, I'm an extrovert, and quickly become depressed without being able to have that morning cup of coffee with someone, or to be able to tell someone who cares. I don't have a co-founder, and I haven't found one who would fit that doesn't have something tethering them to a regular paycheck. I can't even happily work from home for anything longer than a few days - I get very depressed.

Without coworkers, I'm worried that I'll fail. I'm not worried about hard work - I'm worried about my own psychological health.

I would love to hear some stories, from anyone who has faced a similar situation.
