oh CathyMac I am sorry that the Bitch called BC and its associated treatments are impacting you like this....
Can you look at a trip when this is over and son is on Uni break I promise you Uni semesters are short... My daughter is in 4th year and she seems to have more breaks that Uni at times.... she finished in early October and doesn't go back until the first week in March .....
It is ok to be pissed off by this constant upheaval of well laid plans for your family. but as the others have said ... it will finish and you will have given it your best go at being around for a long long time.....
I would also say that during treatment our emotions are so fragile and volatile to begin with never mind that you have had to sit back while he leaves the nest when in fact you want to be a part of this step out of the nest....
Try to focus on the fact that soon treatment will be over and he will enjoy visits from you with Meals and food that can be a luxury for Uni students... You will make memories and remember he is proud of you.... for doing the hard yards to be here longer....
Hugs
