Nowhere, I admire your strength of will to keep trudging forward. Heather is right - you have a lot on your plate right now and for quite awhile.
You are such a sensitive person. I am sorry about your mom - mine hurt herself a while ago and she has refused to go to the doctor or accept help from me - she crawls from one room to the other doing housework. So I can relate.
Please find the time to take care of yourself. You certainly deserve it.
Lots of warm wishes and hugs,
Mary Alice
