@Cyclo I think its more normal than you realise. Mine hit fever pitch through chemo, I became very aggressive and Im normally placid. You know what I honestly believe it is?? and for me I worked this out through chemo...it was my lack of control in the situation, it was my life being turned upside down for such a long time, I was tired and missing my life. Im now 18 months post chemo, 4 months post mastectomy/diep flap recon. FINALLY...through the help of a naturopath and an exercise physiologist am well on my way to a better me. I feel better in myself than ever before, and I was so ill through treatment. So I find your tolerance is no longer what it used to be and really? why would it be. You have to fight to get through so much crap....to come out the other side...so trivial things dont cut it anymore. So for me yeah, more the frustration of it all...it will settle in time. xx Melinda
