I dont want to go to college anymore

I am a non traditional student, 40 yrs old. Long story short, 12 hours, 11 yr old daughter with very rare spinal disease, has sever pain, and a MAJOR surgery is about to accrue. She has psych appointments and I do weekly, she has PT
I have 8 weeks left and I feel like giving up. At this point I return homework less then my best and my tests, well my professors would be furious if I throw in the towel because they have been so gracious to me
I am going to school this morning but my mind and body is screaming not to.
Please give me some encouragement
