Does building something to fight loneliness make you lonelier as a founder?

There is a strange irony I have been sitting with lately.

I am building an app specifically to help young people feel less alone. And yet, some of the loneliest moments I have experienced have been in the past year, building it.

No co-founder to debrief with after a bad day. Friends who do not really get what you are going through. Family who just want you to get a "real job." You share wins online and it feels hollow. You share struggles and you worry it looks like you are failing.

I keep thinking about how the startup world celebrates hustle and grit, but barely talks about the emotional weight of building alone. The late nights where you question everything. The feeling that everyone else has it figured out except you.

I am curious if others here have felt this too. Not just solo founders, but anyone building something.

How do you actually deal with founder loneliness? Have you found real community, or is it mostly surface level? And do you think the way we talk about building (or don not talk about it) makes the loneliness worse?
