I'm not going to be a huge help, but what are your safe foods? Maybe start with replacing takeaway with heated at home? Many takeaway fried foods come frozen in the grocery store and heat quite well in an air fryer. Others microwave half decent.
Eventually, maybe grab a new thing from the store to try out alongside your normal food. (I have a huge habit of ordering an extra thing from restaurants to try things though, so this may not help you much. For me having a backup let's me explore a bit more)
