FID Questions

I recently posted about my testing progress. Sadly I just flared up big time on my hands. I honestly am not quite sure what caused it. I tested egg which I reacted to (although I may be okay with it baked in cakes - I definitely had a reaction to egg on its own) sweet potato over a couple of days (seemed ok), tested a bit mango (to which I had a mild reaction) I then moved on to test carrot, all was okay for a few days then my hands flared up. I do wonder though as to whether I need to rethink the way I test. I am not sure my skin can tolerate testing one food then moving on to another after a few days? Am wondering whether I should simply test one food for a couple of days then wait a week before I test another? My issue is that when I think I have passed a test as I thought I had done with sweet potato, I then immediately start to eat large quantities of it (as I am so desperate to eat new foods having been on FID for nearly 7 months!). I was continuing to eat sweet potato whilst testing carrot and maybe the combination of the 2 was too much for my skin. Also I was eating a lot of marshmallows recently whilst testing. Again, I feel so deprived, when I think I can have a "treat" I do tend to overdo it!!!

Any views/guidance appreciated. Am getting a bit down about the fact that when I try and introduce new foods I seem to react to all of them!!! I am desperate to expand my diet again!

Thanks!
