Am I going crazy? Is my mom right?

I don't know what I'm doing wrong but I can never tell what's going to happen when with my mom. She snaps so easily on me.. She snapped maybe like 3 times today and a few times yesterday.. this happens regularly but I'm failing to understand what I do wrong. Can I talk to some parents and ask if this is normal? Maybe a different perspective would help?
