I can’t draw anymore

I used to draw a lot a few years ago. I’d draw cartoon characters or even create ocs but then I stopped because I was really really focused on my studies. I eventually forgot about it but now I was suddenly reminded out of nowhere that I used to draw and so I wanted try again but I couldn’t. It’s Like I’ve completely lost the ability to draw because now I can’t even draw faces like the proportions are all wrong and all that. I’ve been practicing again recently but it’s nowhere near the same as how I used to draw.
