Away fans at Citizens Bank park

I’m an Astros fan originally from Houston but I now live in the northeast area. I am going to the game on the 26th in Philadelphia. I was wondering if anyone knew how the environment is there for away fans. I’m very nervous because I’ve seen videos of people getting beers thrown at them and stuff. I am hoping to just sit and enjoy the game without any problems but if someone has some advice or experience there as an away fan I would appreciate some advice
