I've been skipping school quite a bit..will it hurt me?

I've been skipping school quite a bit. Maybe 1-2 days a week. I just want to know if it'll hurt me....like I'll end up not being able to graduate or something. My GPA is fine, I get all my work done and homework made up. I've already been accepted into several UCs but I've been feeling guilty and nervous about having skipped so many days. It's just after my mom died near the beginning of the school year due to a kidney failure, I just feel too depressed some days to go to school. I'm trying not to let it affect me too much though; I'm trying hard to just get through senior year.
