do you think I'm...I guess sensitive ?

So of course the school year had ended and this year really sucked cause I felt alone cause I dropped my friend cause I was sick of her teasing me and my friend ( J ) I mean I know it kinda like weak or whatever but it was nonstop teasing not just from her from everyone in my "group" and ever since every one has been leaving not just me but our little lunch group and then they had made a group chat every one is in it every day every second of course somehow I'm the only one not in it and it just honestly hurt a lot but I just let it go. So as the weeks gone by everyday they had plans and no one ever told me anything and if any thing had happened I'd be clueless and ask and they would say " your always late on everything and I would just sit there and think well of course no one will tell me shit and again everyday just over and over and I'd act like I don't care or whatever well one day I found my self crying to ( J) in the middle of math class with make up smeared and a red tomatoe face and I've just been alone since and yesterday one of my " friends " actually read and saw and asked me we ended up having like one of those 2 in the morning conversations it felt good but no matter what I will always have those feeling so I guess I'm asking do I seem like dramatic ?
