Fake friends?

It's been about three months since school has been out and all my "best friends" Have not talked to me very much over the summer break. Like I like and comment and text and all that and they just ignore me most of the time. Whenever I ask they just say "I'm working like 24/7 lol" And "ugh so busy" But then post about being bored and hanging out with their other friends. now that school is about to start I started getting texts from all of them saying how much they miss me and can't wait to see me at school and all this crap. (We are all seniors now) nobody asks me how lv been or what I've been up to and I'm just like ??? We were all tight and crap during school and y'all ghost me basically only to come back and act like it's all the same again...should I even bother calling them out on it or like do y'all think I'm just over reacting?
