Ak,
You are always an inspiration to new members on our forum. I read what you say and always think, Wow she's a very encouraging and compassionate woman. She would make a great friend. So..... now I need you to be that same friend to yourself. Turn those thoughts around and talk to yourself like you talk to others on here.
70% of what we tell ourselves throughout our day is negative, worst yet most isn't true and NEVER HAPPENS.
I know it's easier said than done , but consciously listen to your self talk and change that negative to positive compassionate self talk. You will do fine through this surgery and you will recover fine as well.
Just belive! You got this!
