Is it normal for me to have a life crisis at the age of 20

I turned 20 a month ago and Jesus I’m Fucking miserable right now. I have no idea what I’m doing and I’m lost. I don’t have a purpose in life and I’m studying at a university I regret going to, getting a degree in something I could give less of a shit about, hell my grades aren’t even that good. The intrusive thoughts I used to have once in a blue moon have been much more common lately and recently I had a friend die. I had a dream right before he died where he visited, we played pool and drank and then he shook my hand and told me how nice it was to see me, 2 days later I found out he had passed away.

Trying to make sense of it all and I can’t but life’s moves on right? Doesn’t certainly wait for you to catch up
