Deleting Facebook friends question?

[BRi]

I recently graduated college and started my first job. Now I had over 530 friends on Facebook, but found my news feed to be cluttered with people I didn't care about. So after doing some research, I decided to delete my friends list to the Dunbar number of 150. (I now currently have 140 friends.) I kept friends from high school that I hung out with a lot, people I met when I studied abroad (never know when I'll go back to Europe), people I saw regularly in college, college roomies, some coworkers from my part time job that I went out with, some coworkers now, my family, and my boyfriend's family. Now tell me, I'm a 21 year old girl. Was that strange of me to want to do? I thought I'd feel better about my Facebook after I did that, but it made feel weird and a little anxious.
