My suggestion would be to keep your eyes on the prize. Disappearing takes time away from your goal. This is a time in your life when you want to start attaining goals that you have set for yourself and completing your work at the University sounds like the most important thing in front of you. You want to be thinking about your needs and goals and prioritizing your own self care.
What also seems clear for right now is that these two relationships became overwhelming for you emotionally. This may not be the best timing in life to try and balance a serious relationship with your studies.
I would set my priorities so that you can accomplish your goal of completing your work at the university. After that you may want to look for more intimate connection with someone.
