Fellow 19 year olds, are you feeling anxious turning 20?

I'm about to turn 20 in a few days, I feel sad that my teenage years are coming to an end. COVID snatched my precious years of my school life. Last few years just flew by, I feel like it was just yesterday I was 17yo, I'm still clinging to a lot of things of the past, I want to start new and fresh. I haven't achieved much yet, I feel strange kind of pressure upon myself to not waste my 20s like my teen years.

Please tell me I'm not the only one going through this. How are you all coping with this?
