I know exactly how you feel. This past week has been a rough transition for me bc I did a 180° and switched my major. I have other personal issues going on, and it’s embarrassing when you’re sitting in class desperately trying not to cry, but then the floodgates open and you’re at the mercy of your really sweet TA. It’s a lot, and I’d rather cry privately instead of publicly, but it seems I have little control over it and that has been the case my entire life.
