Hey tehluckster,
I'm sorry to hear about what you've been through--but think how good it is that you found out!
I'm sure that you're feeling really scared about now. It's not unusual for something like this to make women feel really vulnerable! Do you have any support groups through your hospital or your doctor for women who have gone through this? I know that resources are available if you look around a little bit. You'll find you're not alone!
Your title is "minor setback," and it really can be a minor one!
Concentrate on eating healthy foods to support your recovery--and stay away from junky foods that might taste good but only add too many cals. You already know what to do!
Mild exercise would also support you. Is there a place where you can walk?
Just know that you're doing OK! Maybe you have gained--get up your courage and find out one of these days--but in the meantime, get back on your plan, one day at a time.
You can do it!
Jay
