Hi,
How are you? I'm sorry to hear what you have been through for the past months.I agree with Douglas that you need to see a specialist that will help you and your mother cope with what is happening. Both medical and emotional issues should be addressed to help you manage these anxiety issues. Take care and do keep us posted.
I would try seeing a therapist who specializes in medical and health anxiety issues,,, they can help you to cope with your new life.. I wish you all the best
Douglas
