HI @Sharonb58, your headline says overwhelmed.
I am guessing you have a diagnosis. It is very overwhelming at the start of a diagnosis. I cried for 2 weeks when I got mine. That was 30 April 2020. I had surgery, chemo and radium which finished by November 2020. I feel good now.
Take it one day at a time, step by step. Keep busy so you are focused on some other things, if you can. Big breaths, muster support around you. Take care of you before all else.
If could tell us something about your situation maybe the wonderful people here can help you. Big hugs
