Hi Rachael,
I don't know that we ever get our old lives back but I don't let the little stuff stress me anymore. Life will get easier, keep ticking off the treatments. I found chemo the hardest. Radiotherapy was much different & I did end up very tired and my skin broke down but still not anywhere as bad as what I found chemo. Her2 is tough, the treatment seems to go forever but thank goodness we have herceptin. Some women have no side effects but I know by the end I was incredibly tired. I don't know if it was the treatment or just the mental toll. I'm happy to report 2 months out from the end of treatment my energy levels are really coming back & I'm feeling good, positive & energetic. Give yourself time & be gentle. All the drugs do affect you but fingers crossed they're doing their job.
Hugs to you. It will get better,
Barbara xxx
