What should I do?

Well when I was in highschool I had a lot of friends and could meet new people very easily. I was a drunk and on any other substance I could find so most of the people I knew I unfollowed and stopped talking to when I moved out of the state. Well fast forward a few years and I’m back where I grew up and kind of want to reach out to some of the people I used to know is that a bad idea?
