First, while you are going to school (assuming a college or university) you should almost always have access to a subsidized Therapist where you can have really helpful one on one discussions about your mood and anger and whatnot. I'm not saying that you 'need' to go, but that it is really helpful, and I think most people should go see one every once in a while, especially while under the stress of school.
Second, make sure that you have a healthy amount of baby time. Diapering up for the weekend and getting into your little side is probably a good time, since the weekdays you are probably busy. I'd say it is a good thing to escape your adult life every once and a while, so give yourself a schedule when you get to do that. You will have to make sure that you don't allow yourself to get too entrenched into it, regression can be hard to want to get out of, so make sure you are ready to adult up when its time to go to class or do homework. Just try making a schedule for yourself when you are allowed to be little, and when you are going to need to be adult.
Do you have any problems with avoiding room mates when you need to be little?
