Best way to go about getting off of SSI?

I'm on break from school right now and can't wait to go back! I'm going for my second master's degree and I REALLY want to get off disability when I'm done with this degree.

My disabilities are PTSD, OCD, GAD, and SZA (w/ bipolar II). I also have scoliosis and can't stand for long periods of time because of it. I also have a pituitary adenoma, but that doesn't really affect me...

I'm wondering about peoples' experiences about getting off of disability, specifically, SSI. I've been on it since I was a kid! I do work a little bit (part-time, obviously), but I really want to manage a full-time job once I'm done with school. I think I can do it since I can manage full-time school. I actually think it would be better for my disabilities if I were to have a job that I really love because I do BETTER when busy.

I want to do this the best way/easiest way possible. What are your experiences? Thanks for listening.
