is food aversion a symptom?

I recently got diagnosed and I've realised that my food aversion started around the same time as my other symptoms. in the past I've been able to eat foods that I don't like but now I can barely eat more than a few bites without my body stopping me from eating. I also have started to really dislike foods that I liked before , like I just physically cannot eat it. this is a really bad thing for me considering I'm extremely picky and there aren't many foods I like in general. my parents also cook for the family and I'm busy with school to cook dinner every day so cooking for myself isn't much of a thing yet. because of the food aversion my diet is very poor and it consists of things like sweets/junk food since those are the only things that appeal to me. I'm trying to find healthy food I can eat but its so difficult because I'm averse to so much that even thinking about eating it or smelling it makes me feel sick. does anyone else get this or is it just me?? if you have, is there anything that has helped?
