I don't even know how to go about this story

I am writing this because I want to tell someone how I feel without hurting other people I care about. So, I am from a small town where my graduating class had 13 people. So there wasn't that many options for friends. In our small town we mainly had locally owned business. We did however have a chain convenience store that I worked at for a while. During the time I worked there we had a lot of different crew members that were in town working on different things. Well I had became friends with one of them and we talked and started to hang out. He would come over to my house and play video games or watch movies. Well I live with my best friend so she was also hanging out with us. A couple weeks later he got in trouble with his family and they kicked him out of the R.V he was staying in so we let him stay at our house. We three became pretty close friends. Then they started hanging out without me and becoming a lot closer, I felt like I lost my only friends in this town. I had other friends, but I stopped hanging out with one of them because I was trying to be a good friend to my roommate who had feeling for him and got her heart broke when he didn't feel the same way towards her. The other was just busy all the time or I felt like they just felt bad for me and that is the only reason we hung out. Anyway, for the few weeks he had left here they got really close. They started dating. Then everyone kind of saw how hurt I was by this. So they all assumed I had a crush on him, and maybe I did. I just don't think anyone like him would like someone like me. I am not attractive any form. So I became depressed and just wanted to be by myself. I didn't want to tell them that what they were doing was hurting me because I feel like the reason i was upset about all of it was stupid, like I shouldn't be sad because of it. Now I am trying to be happy so I have been trying to be around people. It worked for a little bit until they all just left me to hang out with her again. so I fell back in the hole and became depressed again. Now I don't have anyone to talk to and I want to be happy, I don't want to cry anymore, and I don't want to be alone. The problem is I live in this small town with people who are always on drugs, or people who already have their "group" and no one is allowed.

Honestly I just got tired of sitting here alone and I wanted to talk to someone about all of this and since I don't have anyone to listen I started typing. This thing is probably everywhere, but ill be okay for a little while since I got some of my problems off my chest.
