Sorry to hear you're joining us, but it sounds like it's been caught early & thank goodness for that.
Getting diagnosed, is a shock though & it does take a while to get your head around it, but we all get there.
I'm now nearly 3 years down the line & doing just fine, as the vast majority of us do, recovery is the normal outcome.
I also had an MRI, it is stressful going through investigations & the mind can go into overdrive on the 'what ifs,' but I found it helped to tell myself that it was necessary to get the best treatment plan.
If you haven't already, do look at the other areas of the forum where you will be able to chat & get support from others where you are now & those of us further down the road.
