I can totally relate to you. And you are not alone! I was so surprised when I found out only this year how many of my coursemates actually hate engineering.
I've been studying Electronic Engineering, I'm about to graduate this July and I never ever want to get an engineering job. My advice is to just finish your degree, and you can apply to pretty much any job after, make sure you volunteer and get some other skills.
To be honest, although I hate engineering, I feel so proud of myself that I made it so far and got good grades in one of the hardest courses.
You can always apply for a masters or a PGCE Maths.
