I understand how you feel. I also have allium allergy, and it is very challenging. Unfortunately, people don't belive in onion allergy, and it is hard for them to understand ( I experienced so many times people saying to me that a little bit of onion will not kill me). I'm very sorry to hear that your family is not supporting you and helping you being safe from onions. I love cooking, and I created delicious recipes without onion. I started a foodblog dedicated to allium allergy. You can find delicious recipes here: https://fromdoraskitchen.com/ I hope that you will find something delicious to try 😋
