Sorry to hear you're having more waiting and worrying. I had 3 WLEs 5 years ago, and none of them was particularly different from the others, apart from I had an infection after one of them. The thing I felt later was the effect of 3 general anaesthetics in 7 weeks, which affected my memory quite a bit - but it slowly improved. I found it hard to build up stamina from then, but I was 65 and maybe slowing down just a bit anyway.
I had radiotherapy following my ops, and found that to be a straightforward procedure and not at all worrying - I was lucky in that I lived close to the hospital, so didn't tire due to the journey as some ladies did and also that I didn't burn much at all. The difficulty for me was severe pain in my shoulder/breast area due to lack of movement, even though I did the exercises - that made raising my arms for treatment extremely painful - apart from that it was fine. Months later I found that there was a specialist cancer physio, which nobody had thought to mention. Apparently there are these specialists in many hospitals, so anyone with problems with lack of movement should ask about seeing one.
Take care and remember to take it easy and be kind to yourself - it's very early days for you just now.
Gentle hugs, Jo x
