Working a 9-5 during college.?

Hey guys! First and foremost thank you all for taking the time to let alone read this... My question, I'm sure applies to many of you. I'm a Senior in high school and will be starting college in the Fall term of this year. I'm currently working a part time job at Publix and I can't help to notice it interferes with my school schedule... What I'm wondering is, just how hard is it to work a 9-5 while in college? Is it manageable or just way too stressful altogether? Any advice will be appreciated. I'm just exhausted with my current regimen. It's school, work and then school work. I'd rather just something continuous. I'd love to hear what you guys think... Thanks :)
