My bf has been developing a lot of health issues so I'm trying to make healthy meal prep for us, but I've been told I'm a terrible cook

Hello. My bf has been actually losing weight the past few months due to health issues, and I think it's important for us to eat healthier. I've been trying to meal prep but I'm being told that I'm a terrible cook. I'm confused because I don't think I'm a terrible cook, and things I make don't taste bad to me. I'm really not sure if I'm just being defensive or if I'm getting gaslighted. I do know that I have a hard time taste testing because I have copious amount of sinus pressure due to allergies and a deviated septum. I'm planning on getting my septum looked at soon.<br><br>I know a lot of people complain about meal prep being bland, but I add seasonings and herbs. I'm really not sure what to do at this point. I'm getting really annoyed that my cooking is being insulted and I'm confused that the food I make is somehow inedible to him and everyone else. I haven't been told that I'm a bad cook until recently. I'm just confused.<br><br>What's happening? I'm just really confused and hurt and want some help. I just want to make something good for my bf.<br><br>Edit: I meant to say " developing a lot of health issues" and not "losing a lot of health issues" lol I'm a dummy<br><br>Edit 2: I know some of y'all said I should be the judge of whether the food is good or not, but I'm just having a hard time trusting my own food after being told it's bad. I'm going to keep on cooking and I'll maybe try to get some feedback from others.
