My personal life sucks right now

ever since I've graduated from HS I've completely lost touch with ALL of my friends except for two but they go to different colleges so I rarely see them. I thought moving to DC and going to Community College would be a great way to meet new people and make new friends but boy was I wrong

I haven't made any friends yet and I never go out like I used to in HS, sure I had a couple of classmates that would text me about class assignments and what and I talked to a few outside of class but it's really really different, in HS I was so used to being around a lot of my friends and associates which meant that I always had someone to hangout with and talk to, I have none of that now and it really bothers me. Is there any suggestions? I miss being myself ever since I've entered Community College I've had to change my entire personality

I'm a lot more reserved and quite and it's killing me.
