You are under a lot of stress because much of your comfort zone, I suspect, is changing in very radical ways. Divorce is never easy even if your parents have been separated. But, you need to process and manage the decision to divorce. There is never a good time for this to happen but because you are in school, I imagine that this is highly distracting for you. Given that your Mom is selling the house that you grew up in, you are also dealing with moving away from that part of your life which, when it is a family home and perhaps where you grew up, is also challenging you to move away from security into the unknown, but you can do it. Your courseload seems quite heavy. Is there a possibility of getting an extension? Postponing a course? Some compromise? Perhaps a study buddy might help? Maybe none of these possibilities is available, but think about them just in case.
Eat as healthy as you can which can be difficult on a restricted budget. You are doing a super thing with walking and stretching. Both all excellent activities especially gentle stretching before bed to relax the muscles. If you are so inclined, perhaps try some mindfulness to count all your positive attributes. Yeah, I know, but life is pretty negative, but you a a valuable positive force so strengthen that by actively remembering it.
I am so pleased that you are doing better. I sense a very strong sense of spirit and you will survive your parents' divorce and manage your anxiety. You may have to take a step or two back, but in the long run, it's only a step or two back in order to go giant leaps forward. You do not seem like the type of person to "give up because something is too hard" but, like all of us, sometimes you need to postpone, heal and recovery, and then move forward.
When you can, let us know how things are going . . .take care, "no longer helpless dancer," . . . KC
