Your a wonderful Mum and definitely not crazy CB.
I think it's better for you to make a decision yourself and not sure why the psych would impose a timer on you for you to decide. Seems like thats unfair pressure.
Would you be comfortable with a friend or stranger stepping in for you? Would your eldest be able to do it for a while? My concern would be the time line and how long you will need. Can you take a time out at home or do you need more than that?
I really don't know, everything is diffucult when you have other people to consider and take into account.
Lots of good wishes CB, wish I had some wise words or suggestions for you.
