I’ve experienced the frustration of having a dismissive doctor too. It’s an incredibly discouraging situation not to be heard. So I’m happy that you were able to get the help you needed!
Now you’re in full recovery mode! From experience with cancer treatments it just takes time to heal — mentally and physically. It’s a challenge to be patient when you’re just bursting to get back to normalcy. ☺️ But there’s no rushing this step…it’s slow and steady for the win. So, for the time being, you get a free pass to veg out. Your body will tell you when you’ve overdone!
Walking is a great way to build stamina by slowly adding a few more steps, blocks, miles, daily. Keeps the blood moving, endorphins flowing and heart pumping!
