needing encouragement

Jordan
I'm 36 weeks pregnant and a full time mathematics student. My plan was to graduate this fall, but I took too heavy a course load and am struggling. It looks like I won't pass 3 of my 5 courses this semester. I feel like a failure and hate that I have to tell my parents, again, that my graduation is being put off. The one thing I promised them when my fiancé and I told them we were expecting was that I would finish school. I also feel like I'm failing my son and fiancé. I really just need some encouragement or a good way to tell my parents I won't graduate and am considering even dropping out.
