Regret joining sell-side, looking for advice

Title says it mostly - I spent the last ~3 years working under an absolute rockstar analyst at a boutique research shop (think II hall of famer who started his own gig) and so never got the 'traditional' sell-side experience. Setup there prohibited us from joining our clients so I wasn't able to pursue that route and figured I'd join a bigger brand name / more traditional sell-side shop to then move to the buy-side. So I did that at the beginning of this year, however it's been an absolute nightmare. The work is totally devoid of intellectual rigor (we just model to the guide and arbitrarily plug numbers). My boss is green to the space and frankly doesn't know what he's doing (he's objectively wrong on most of the things he says and has a limited grasp of finance). He's had high associate turnover and lives in a state of paranoia because of his past mistakes with clients, so I'm subjected to constant fire drills on a moment's notice regarding old work / numbers that at the time I'm not aware even exist (done months/years before my arrival). The result is feeling anxious all the time and like I'm unlearning old/good habits. My question is two-fold: 1) is this normal on the sell-side and my expectations were just set too high previously and 2) should I go to my manager / talk about switching sectors and my situation or just take the L and try to join buy side? Any thoughts or feedback appreciated.
