Is it normal to feel nostalgic about even 2021 and feel 2021 was a lot better than 2022?

I feel nostalgic about 2021 now even though it was last year. I was 20 and in my 3rd year of college and then entered 4th year in October. In Nov 2021, we went to Udupi in train and it was a memorable enough trip for me and its already making me nostalgic now. 2016 is still my most nostalgic year tho. Honestly being 20 seemed better. Now after I became 21, I had been really sad and scared that I am getting older. Sometimes I feel kinda old. 2022 feels like a very sad year as I am about to graduate college after few months and I am really sad that college is almost over whereas in 2021 I had an entire year of college left. 20 is still considered an young adult but many considers 21 to be officially a grown adult and thats making me sad. I often have been feeling like crying and often sad songs come in my mind which never used to happen in 2021. I think 2022 is gonna be my saddest year.
