Friend - I am so glad you had a good day going to the orientation.
Whine all you want. It is OK. Let you DH take care of you for now. Once you are back up and running it will be your turn to take care of him. I am sure he wants to do things for you right now. I am sure DS and DD want to also. Allow them to do things for you as well. Honestly, it will make them feel better as well.
DD18 and DD16 have learned quite a bit in the past few years and it's OK. I was like you at 1st but since I'm a single mom (DBF and I don't live together) and there have been a few times, much to my horror as well as theirs, that they have had to help me in and out of the tub.

(I think DBF would enjoy it far more than DDs

lol)
There are times when they have give me massages to work out the back spasms, help me walk, etc. I do, however, encourage them to be teens too and I know they appreciate that. So they have to massage my spastic muscles before going to the movies with their friends. That is OK.
I do hope you feel better soon. It is scary to have these crazy things but you are not alone in this crazy stuff. We are all here with you and for you. Sending good vibes, prayers, and gentle right-sided cyber

's.
