Hey Stuart, there are no frauds when it comes to CML. If you have it, I'm afraid to tell you that you are not a fraud! You really have CML, you really have cancer and that's the end of that. You've "chosen" one of the better ones, or at least your timing is good as we didn't always have the treatment options we do now.
That rash might be petechiae. Search Google images for that and if it looks a little like that (the results will show severe cases the most part, so maybe search for "mild petechiae") then that could be it.
It's usually casued (in CML patients) by low platelet counts, which is pretty normal for a newly diagnosed CML patient.
Tiredness is super common, not least because of the mental strain but your body is going through a lot with all the new medication, etc. Things should start to settle after a couple of months, so once you it "CHR" (complete haematological response - i.e. your red and white blood counts, and a few others, appear normal) it's time to consider mamaging any remaining side effects. But with luck, things like tiredness and rash will start to dissapate and you will feel much better. If not, there's things that can be done about that for most patients.
