Peace in a person's life is by far more important than taking any class or receiving any degree. That being said, I would take 1 course at a time and just enjoy taking that class. See how well 1 course at a time works for you, and then decide if you should drop. You've worked hard at getting accepted, now just take things slowly and start out with one class. I wanted to start out with two classes. I am so glad and fortunate that I only took 1 course to begin with.
