Am I the problem

The thing is that there is something happening like the thing is the place I went to cc in 11 is the same place I go for in 12 but what happens was when I 11 I got there there was only say X ,Y ,Z ( boy) and me and I knew X before because we were in same classs and then in 11 she left school and I was still in that school and at that time X andY didn’t used to talk Z now what happens was during my finals since I felt that we weren’t studying much and like I felt like also my course was due in physics so I felt like not going to cc and then I left and then in 12 I came back and for some reason their behaviour changed towards me like totally now what happens was sir took some 11 and 12 people for trip since I was not there so I didn’t go and after that I think Z nd X and Y were a but was down with each other but I siding when I. Came for 12 again what I felt was they were comfortable and for some reason they were avoiding excluding me and a bit awkward I won’t say but a bit changed twoesw me and then as passage of time what I felt was what X was before she a was not now she became more acc to me a people pleasing person like she used to getZ attention more and for some reason she would acc to her take his id carr and won’t give him to hitch Z also reacted okay playfully but the matter was I don’t know for some reason they won’t include no matter how hard I tried I didn’t get comfortable with them and then there is now I go to school then cc and go a bit late the tiger hand X,Y,Z goes early so their bonding grew strong and I get now again wzcluded and awkard around these people the thing X is a bitch acc to me all she wants is attention if me andY are talking she would say what what what are you talking about and altmeat irritate me and even n Y. wants attention I don’t get it they both especially X wants to know everything and like she would I personally thing now purposely make me feel excluded and for which I get awkard around all of them X has started becoming like that teen manuplative person who wants attention and wants to know every gossip like what happens recently was they went out with sir and mam and then some mthing happens they came to classes after 4 hr and then they would tell everyone the story except me and then when. They had to sit they were like can I sit in middle making me sit in the corner
