Job help!

I have been working at a movie theater for 3 years, I love that job! All my friends work there, it's a great atmosphere. I am also a full time student at a community college, but I decided to pick up a second job in order to make some extra money...surprisingly, I don't work that often between the two but I have been feeling incredibly stressed out lately. I really like the second job and have only worked there twice, but have been thinking about leaving due to my schooling and other job others are telling me to give it a month to see how I feel...what would you do?
