I can totally relate.
In addition to "no one to bounce ideas off" - no one to really share the pain and responsibility with when there are problems. It's all on you.
Thankfully, my users are very generous with their feedback, so when I do in fact do a "nice job" - I'm told so :)
For how long have you been building solo?
After 20 years, for me, I can tell you this - what helps me the most is exercising regularly (ideally on all weekdays) AND having kids.
Because of the kids, I rarely have the time to feel lonely and the regular physical exercises keep me in a (fairly) good mental state.
It felt the worst in my first years of solo dev, when all I did was work and hardly spent any time to socialize and take care of myself.
I'm sure it'll get better for you too as your project evolves and your life along with it.
