Just echoing what others have said. For me, it is adjusting to the new normal. That includes a really tight neck, muscle spasms in the shoulders, some lymphedema, need to dring water with lots of foods, reduced taste. Oh yeah, add in the repeated visits to the 3 oncologists (surgeon, medical, radiation), the anxiety over scans and results and some skin issues that need to be addressed.
Would I trade these for the alternative, which is not being here at all? Nope!! I can do pretty much anything I want to, and just have to be aware of different things and work a few more things into the schedule.
I deal with depression from time to time, but it is getting better. You will get there, just be patient!
