Feeling down

Ive been feeling pretty down recently. I'm gay. Aside from my best friend no one i've told had any idea i was gay. Almost all of my friends (growing up and now) are straight. All of my current closest friends are dating. I'm 24 and I havent dated much, it never bothered me because whenever I got to feeling down my best friend was always there for me. I could tell them anything, they were the one person I could confide in. They've started dating and moved out of town. Since they've moved away we've grown distant and we hardly ever talk. Im not mad for them for moving on, everybody has they're own plans, maybe we'll be close again sometime. I guess im just bummed that I'm pretty much the only gay person I know and I have no one to talk to about... pretty much anything vaguely gay or about feelings like i could with my best friend. Have any of you been in this situation? Advice?
