I feel like I'm the only one out there

I've been feeling really lonely lately. Or maybe not lonely, more like alone I guess. I mean in a way I've always felt this way but ever since I admited to myself that I was/am gay (lesbian) I've been notecing more and more just how different I am from other people. Idk. It truly feels like I'm the only lesbian in my town hell even my country sometimes. I know some bi people so I know I'm not complety alone but sometimes it feels like I can't even relate to them really. And I've never met or even seen a lesbian couple irl. Idk. It also doesn't help that I'm not out I guess.
