OP- hugs. I think you are getting good advice (certainly talking to your professor is absolutely and positively the right next step— do it tomorrow!).
But I want to reassure you that there are millions of happy and productive adults who never took or passed chemistry. And they have perfectly fine lives and careers. So if part of what’s keeping you from totally engaging in Chem 1 right now is you catastrophizing “If I don’t pass chemistry I won’t be able to major in engineering. If I don’t major in engineering I’ll never find another major I like. If I don’t find another major I like I’ll have to drop out of college and I’ll never get a job”.
Stop the cycle. Focus on NOW. Once the semester is over you can figure out if engineering and you are meant to be; and if not, there are dozens of majors you might like even more that won’t require a lick of chemistry!!!
