What's supposed to be acting as your mood stabilizer? The Abilify I'm guessing was added to the Wellbutrin because your depression was getting worse ... right?

How much sleep have you been getting? Cutting to 4hrs may be too drastic, depending on what you're getting now. How heavy is your course load? What's your outside commitment? How old are you? All those things contribute.

What's your usual caffeine pattern? A B-complex load might be better. How are you with sugar?

How long are you planning on putting yourself through this?

You're a smart young lady, so you already know this I bet: No one knows for sure how to stop a depression from growing. You're not accepting the slow-&-steady safer ways right now; you want a short cut. Shortcuts, even when they don't work, can be dangerous.
