@Ellenwatson65 stopping treatment is a big decision, but no bigger, in some ways, than agreeing to start in the first place. If it makes sense to you, that is your prerogative
On that topic, choose your battles when it comes to telling family and friends what you intend to do.
Talk to your medical team first and then tell anyone else who absolutely needs to know. You will get some push back from both quarters, but the personal stuff is harder to manage, so be prepared for some people trying to crawl into your head. You probably already know who they will be so perhaps cut them out of the loop for now.
In the end, they are not living in your body. If you've given it your best effort, so be it. Mxx
