Aww I felt moved to tears reading about how difficult it's been for you. Sounds like you've had a real rollercoaster of emotions.
I agree that it does affect your moods at times and I have also felt resentment. When you're poorly it doesn't help.
As someone who suffered with tonsilitus before having them taken out at 14 I know how you feel. It's incredibly painful. An ice cold tetra might help if you haven't tried already or having your shakes with ice could sooth it.
I used to gargle with salt water and spit it out, but not sure if that's advisable on this diet. Take care x
