It will pass, always found week 2 the worst part of the cycle. Lost a lot of body hair which hasn't really grown back properly 4 months after finishing chemo. Also my ribbed fingernails are slowly starting to grow out, they look weird.
Fatigue, energy levels are back to normal - we have a huge lawn, cut it yesterday and felt fine afterwards - when I cut it in February I thought it was going to kill me.
Patience my friend, take you 3 months to get your stamina levels back, in the meantime try and relax.
