Hi there @Gin1966, it is all such a shock isn't it. I think after I was diagnosed I cried for 2 weeks. It is a roller-coaster but you will get through it. Seeing a psychologist early is great. Good to have all the support props in place. It takes time to process it all.
I am a planner too. I felt better once my surgery was done and the whole treatment plan was developed and I knew all the treatment I had to go through. I had surgery, chemo, radium, more surgery and now tamoxifen. I am now one yr and 2 months post my diagnosis. It was alot to go through but I am doing well and you will too.
One step at a time. Stay as much as possible in the present moment. If you are into mindfulness it is good and so too is a bit of exercise, even gentle walks. Just do what you enjoy and please make yourself the priority.
If you are like many others here we all looked after everyone else first and put ourselves second. Make all this treatment and getting well your number one thing. It was a change for me but it is better not just for me but everyone else too.
Good luck, stay in touch as you go through this as we are all here to help. The people here are all just so amazing. Hugs 🌺
