DIBH anxiety post treatment

Hi I didn’t have anxiety as I have done a lot of snorkelling and that’s what it reminded me of!
I do suffer anxiety about
pretty much all medical stuff and was a complete nervous wreck before my mastectomy and later reconstructive surgeries.
I do know a lot of women have had anxiety with the deep breathing though so you are not alone.
I did find all the staff very caring and helpful where I was so I hope they can help you through it.
im not sure if taking something like Valium would help or not , you do have to stay very still so it might not be right.
Hopefully others on here may be able to give you some tips.
