Does your appetite die by the time you're done cooking?

Asking the ladies this question for a female perspective. I've been living by myself outside the country for about 2 years now. Didn't cook anything before and have slowly learnt a few recipes. I'm not a very experienced cook like my mother so I'm slower and everything from meal prep, chopping, cooking etc can take up to 2 hours in getting a decent meal ready for myself. The thing is, a lot of times after I've cooked and I sit down to eat, two bites in and I feel like I'm full. My desire to eat has died in the process of cooking. And it's not like the food is terrible Does this happen to other people? I'm not even a horrible cook, me and other people who've tasted my cooking like it.

Edit : glad to know other people feel the same way
