New to the club but already felt the warmth

Hiiii everyone, I am new here: I was diagnosed last week and still feel like a dream: I even thought perhaps there is metaverse and one version of me is having a life without breast cancer... Buy anyways, this version of me is here and will keep going no matter what.

I do have a question: does anyone is using COBRA during the treatment, and how helpful it is considering the entire treatment might take long?

Thank you!
