I want to get a different job because my current one is toxic, but I wouldn’t have to be a sales person

I want to get a different job because my current one is toxic, but I wouldn’t have to be a sales person I need your advice, cause I’m gonna kind of tough situation and if you all have any words and encouragement, even that would really help So I am working in a grocery store and I don’t wanna see where but I’m gonna say is it’s in the US and from day one it’s been pretty dang toxic and I’ve only been there about two weeks. They constantly act like me asking something is just the worst thing ever and don’t wanna help or even try to give me any anyway. They’ve also gotten aggravated/frustrated when I talk to them about my schedule since they kind of messed up. Here’s the thing, I am starting to get into cars a bit and a friend of mine works at a car auto parts store which it’s a big name but it’s a small store and although I don’t know pretty much anything about cars she’s trying telling me they can teach me stuff there and they would train me And she could probably get me a job. I have to answer phones and talk to customers pretty much only and I just don’t know what I should do. I don’t wanna be around toxic people, but I’m also very worried about my stutter
