I worked at a computer store for almost 4 years, don’t really have any seniors since the first year and if I don’t understand something google are my only hope

So during 4th year it got worse, I got college final project also tons of work. That last year really burn me out like crap. No one’s complaining if I can’t troubleshoot something (even the boss or client) but I feel depressed if I failed to help them

I quite 3 months ago and currently on another city with a software company, first 2 months was great, tons of senior and I can finally rely on someone instead of pulling my hair by myself

P.S. The store working atmosphere was nice, but I just don’t wanna be last man when shit happens. Especially if it’s my 1st job
