What to do now

So here it goes. I live in Canada, I wasn’t born here but I came here when I was 15. My first friend was this girl named Ana, we became friends cause we were on the same class and we were from the same country. Ana and me, wow. We had this amazing friendship, at the beginning it was awkward cause tbh I’m an awkward person, I don’t trust in too many people and I’m very selective when it comes to friends, etc. but her, she’s very outgoing and crazy and stuff, everybody loves being with her. I didn’t mind that, I mean, she’s my best friend! As long as she’s with me i don’t care about the rest. We were inseparable. We work together, we used to live next to each other. Everything we used to do was together. People knew us as because everything we did was always together. We had our ups and downs, but at the end, we were always there for each other. Until this year. This is our senior year. We’re both 17th and since the beginning of September things started to change. She started hanging out with this girl name Alyssa. Going to football games, parties, shopping, running etc. she stopped having lunch with me and left to go with Alyssa and her friends. That kind of hurt. Distance hurts. I started to think that she left me because of Alyssa. I mean, this girl knows everybody, always going to party and stuff, the kind of girl that Ana is. I started feeling bad and alone, I tried to fix things with Ana because I missed her. She was like my sister and suddenly, she wasn’t there anymore. It was me who had to ask her if she wanted to go out or have lunch etc. the only times she used to talk to me was to ask me if I could work for her. That’s it. I started to thought that this girl Alyssa was her new best friend, so I obviously started to hate her. I couldn’t even seen her cause for me she was always going to be the girl who took away my best friend. Time passed and one day Ana talked to me, told me that she missed me, that she couldn’t call Alyssa her best friend cause she wasn’t me and that she was sorry. I accepted her apology cause she was still my best friend and I missed her too. At the beginning everything was fine again but then… We started drifting apart again. Now she’s really close with this girl named Celia, who’s also very close to Alyssa and me too. They’re always together now. And even if I come and sit with them, I feel excluded. They’re always talking about thing I don’t know and planning going out without inviting me and stuff. I feel so hurt. I mean, I love Celia but now Ana only talks to her, tell her problems only to her, goes out with her and Alyssa… I mean… She left me. The fact that she started hanging out with Celia now made me realize that Alyssa never “stole” my best friend, it was her who left on the first place. That’s why I’m here. Cause I’m hurt. It hurts so much to see that special person, with who you were so close a year ago being so close to other people now. That she doesn’t even bother to call you to hang out anymore. That she has other friends with who she’s having a great time and you don’t mean nothing for her anymore. She was like a sister for me, the only person I really trusted. It hurts to think that she left me, she got tired or bored of me. She met knew people and she liked them better than me. It kills me passing on the halls everyday and seeing her laughing with this girls. Don’t get me wrong, I have other friends too, but I only had one best friend and it was her. I’m not sure if she still calls me her bestfriend, I would be surprised. Cause I don’t call her my best friend anymore. She’s not the Ana that I used to know. And that hurts. I know that I might sound pathetic but this girl and I spent too much time together, I mean, she was my first friend when I didn’t know anyone. I was there for her since the very first day. And she leaves me just like that. I know that I shouldn’t be crying over her like I am doing it know but it’s so hard to move on. I just don’t know what to do know. Cause she talks to me sometimes just to cry over a guy or ask me for advices cause according to her my advices are the best cause I know her better but still, I’m not a fucking Kleenex, don’t come at me only when you’re crying and then leave me and talk to me 3 weeks later. I really thought this girls and I were going to be friends for a long time. I’m tired of trying to make things work. I’m tired of people. They don’t treat you like you treat them. They put you as a second choice, if you’re lucky. I’m tired of people leaving me. Like, sorry for always being there for you, I didn’t know that that could be really annoying. I guess that it won’t happen again. I just wanted to share this. I’m not suicide or anything, I know that time heals almost everything and it will get better but well… I guess I’m just hurt.
