Fear around developing food allergies

For the past two years ive been scared of developing food allergies specifically anaflaxis when having foods I haven't eaten in a bit I sometimes avoid eating them al together I always read the ingredients I'm ok with eating wheat and soy because foods I'm comfortable with have them but anything with eggs peanuts and sesame I avoid I also avoid fruit and vegetables I have had salad and burgers in the past months and was fine but I haven't eaten those in a while and my family made burgers tonight and I was too anxious to eat it and I feel like a failure I want to try new foods and foods I haven't eaten in a long time again I haven't eaten bananas since 2022 since the last time I ate them I thought my mouth was tingling my safe foods aren't exactly the healthiest really just processed foods and snack bars I used to eat protein cookies but last time I ate them I had a panic attack and haven't eaten them since
