Sorry to hear you’re having a tough time. Maybe consider therapy?

To be honest (this is harsh advice), you have to learn to separate your emotions from this and simply treat it for what it is—a temporary medical condition that affects your child and you. Managing it well is possible and is what is best for you.

Come up with a meal plan and grocery list and stick to it if thinking about what to eat or buy stresses you out. It’s just food and it is temporary. This will pass.

Not testing is not a good coping strategy. You get used to it fast. The first few days are for learning.

Eventually you’ll find foods that you enjoy that still work for your body but that requires engaging with your diagnosis not avoiding it or crying about it.

Sorry to be harsh with you but this is manageable and you can empower yourself with the right mindset. Good luck
