Having a hard day at school.

Has anyone else been in school while pregnant? I'm currently in dental school 16 hours a week and these last two days have been emotionally hard. I'm 33weeks and we do a lot of standing and interaction with each other and idk if I can keep doing it physically and emotionally. My bf asked how I will go to work if I cant get passed two days this week without breaking down and that really hurt me. I'm trying really hard to push through so I can finish school but maybe it is too much 😕
