Well that is just the pits!
Is this gluten sensitivity only until your body rids itself of all the residual from treatment or is it a permanent feature?
I agree with @Afraser when you are down in the dumps like you are at present it is not a time to be making decisions!
Nothing is ever a waste of time it is about finding what works! I hope something that works is offered to you shortly so you can get yourself into a rhythm of who you want to be!
BTW just read that anemia is a symptom of celiac and a symptom of cancer - BC just keeps giving
Take care xx
