Friendship breakups suck

It’s been about 4 or 5 months now since my best friend decided to call it quits after a couple weeks of miscommunication and tension between us. He had started acting kind of cold and meaner towards me and I didn’t know why and my dumbass instead of trying to communicate about it, I just kind of started giving him the same kind of attitude back. I avoided talking to him or responding to his texts (even though he barely texted anymore anyways). Eventually I did answer him and it led to a conversation between us (we had actually had one already not long before this one but it ended with us arguing so we started avoiding each other again) This second conversation I tried to communicate a bit better but it ended up with him getting mad at me I guess because he thought my reason for being upset with him was stupid. My reason again being that I felt he was acting colder towards me and that he didn’t really care for our friendship anymore. On one end I did understand him because communication really isn’t something I’m good at and I’m aware I need to work on it and maybe I wasn’t able to explain to him exactly how I was feeling. Anyways it got to the point where he just got frustrated and said he didn’t think our friendship was going to work out anymore and that made me literally beg him to give me another chance to fix things because I really didn’t want to lose him as a friend. But he really didn’t give me any more chances and proceeded to block me on everything lol. Unfortunately I’m still not over the situation, I still cry a lot about it some nights and the first few days after were even more awful because it genuinely felt like someone I cared about died, I’ve never felt so much grief over just a friendship, and the fact that he would always promise to stick around as my best friend no matter what just makes me even more upset. I don’t know what to do at this point, I know I should move on for good but it’s been so difficult for me and every time I see something that reminds me of us it just hits me like a truck all over again. I think this experience has left me so scarred that I genuinely am scared to make new friends from now on because I know now it would not be a good idea to get attached again the same way I was to this friend. Is it even normal to get this dramatic about these kinds of situations?

Anyways sorry for the rant 😓
