Sounds like some major decisions looming ahead plus busy times again. Use as much time now to rest and recharge your batteries. I hope this does not come across the wrong way but maybe this all coming to a head means long term you will have wider support from the 'professionals' too.
If, and this is a big if as we have no idea as yet what hospital will decide, if they try send your mam home by relying on even more input from yourself, take a stand and say no. Will be hard to do but you cannot go on like this Pam. They will need ensure her safety so could be looking at some respite care being provided whilst assessments take place.
