This job is ruining my mental health

Is it just me? Had a huge panic attack last week, and I come home at least once a week feeling like I’ll have a nervous breakdown. I’ve been doing this for almost 3 years now and I keep hearing “it gets better”, but it doesn’t. I’m tired of being thrown to the wolves. I’m tired of being blamed for something I had nothing to do with. I’m just tired of construction industry as a whole.

Also, I recently failed the N4 course (zero prior experience). Coworkers told me they worked with it in the field for at least a year before attempting the class, but stressing over failing nonetheless.

Can anyone advise what they did outside of BAS? I can’t do this anymore…
