I can’t trust people at all

I hate it.

Close friends I’ve had for years. Feels like they secretly think I’m an idiot.

Client who trusts me with their entire web design project. Feels like I don’t know anything and am providing a sh*t service.

Communities or workplaces I’ve been a part of for months or years. Feels like I’m always the lowest performer.

Random people that walk up to me in the gym who just want a spot or workout buddy. Feels like they’re about to punch me.

Sometimes I get clarity from it. Maybe a few hours (or 1-2 days at most). My fear is the rule, not the exception.

Anybody else experiencing this? How have you overcome it?
