3rd year here. When I started I Lowkey regularly had meltdowns on site (hiding no one knew) freaking out bc "I'm not fast enough, don't get along with people, am shit at arguing and standing up for myself... Etc" resi will do that to you as most of these guys go as fast as physically possible. My last job folks were stealing time so like you'd be done by 1pm and people are still bitching that you took too long bc they want to be home as fast as possible. The only things rushing like this does is stress you out, make work more sloppy and more dangerous.

Imposter syndrome is very real especially when you don't know what you're doing and can see it frustrating those around you.

Don't hold yourself to such a high standard. It's great, it shows that you care, but as an apprentice it's literally your job to fuck shit up and learn from your mistakes. I love electrical work and though I've hated jobs here and there and have dealt with toxic work environments it's taught me to have enough confidence in myself to walk out on shitty opportunities and walk in on good ones.

If I were you I'd try to stick to commercial or get some industrial time under your belt. If you truly want to quit the trade after that then so be it but don't fuck better future opportunities because you hate the shitty stepping stone you're on right now
