Sorry your beardie isn't feeling well
What are your basking temperatures and what are you using to measure them?
How long has she been eating supers? You may want to start feeding supers in the AM so she has more time to digest them and then do crickets at night.
To help with the poop, you can feed a mixture of chicken and squash babyfood (I use Gerber, but I'm not sure what you have available in Ireland), applesauce (no sugar/spices), and/or pumpkin (no sugar/spices). You can add a drop or two of olive oil to any of these to help lubricate the digestive tract.
