What's going on?

Originally posted about this in a different subcommunity but someone suggested I try here.

Not sure if this is an eating disorder but lately I've been developing fear surrounding certain foods. And, for context, I've always been a pretty big foodie, no body image issues or anything like that.

Some foods that I used to like, I have a hard time eating now because of taste or smell. And others I'm struggling with because of texture; sometimes it takes all my might not to freak out, keep chewing, and swallow.

I've stopped eating several things in a relatively short period of time but I feel the nee to push myself sometimes because I know that by giving in to the fear, I'm making it stronger. I know if I get into the habit of avoiding what's scaring me, I will be able to eat less and less over time.

Has anyone else experienced this or have some advice on what to do?
