cannot get sick

I cannot get sick.  DS is depending on me. DH cannot do what I have to do to help DS get into college with accommodations. i have to drive him all over to get dr letters, meet caseworker from county so they can help get and keep a job.  Go to class with him till they can get a note taker for him. 
I cannot fall apart.
 DH works all week in and out of town.  He is going with DS to first math class, thank God. I have to go to the rest and drive him because his ither classis are downtown and difficult for a seasoned driver to maneuver.
DH has also agreed to clean the downstairs for me because I am almost non functioning by the time I get home with DS after all of the meetings ect.
