Is horribly worried...

I have these two friends well one friend one ex-friend
I talk about them every now and then their names are Crystal and Eva....
Well here is the situation, Ever since several years ago me and Eva haven't been friends, as for me and Crystal we kept in contact till a few months ago.
I knew when her grandmother passed it was hard, she had to move to her Aunt Kims, and change her number.... well we went to one rollar rink where an incident happened and then after that.... well only a few more calls then nothing....
For a long time nothing.
When I finally found her again she seemed to give me an odd cold shoulder, wanting to ignore me, in fact she was busy catching the bus, but even that was unusual... no hug? Normally Crystal is a cheerful bright girl with jokes to give all the time. But when she ignored me yeah...
Then the past two times I talked to Eva's mom I found out they were fighting... for 2 months those two have been fighitng?
Last I checked Crystal HATES fighting, this was unlike her, I just talked to Eva's mom again because Eva still refuses to talk to me.
Turns out, Crystal well.... Now I'm VERY worried. Crystal is my literal childhood friend, I've known her since Kindergarden NO JOKE, what Eva's mother was describing.... that was not the Crystal I know.
Something is wrong. I keep feeling it, every attempt to contact Crystal hasn't worked either.
According to Eva's mom well Crystal has been acting bad to a lot of people as of late. Here is why this isn't like her, this behaviour sounds like her annoying brother Patrick.... but even Patrick wasn't this big of a dick, sure Patrick was a jerk, but for Crystal to turn everyone off, get in fights?
I'm sorry guys, I'm just getting extremely worried for my friends out here.
We used to be quite a team before back in High School, used to do everything together even.
Did we all just grow up and apart?
If only I could find Crystal, it seems my original hunch that it was Eva at the root of this was wrong, this situation.... is about to get far worse I fear.
Now that I think on our old friendships we all used to laugh and smile a lot yet it seems I'm the only one trying to keep this crew together, and yet I can't even find them.
Funny.... I always was the oldest, therefore I always did have to look out for them.... I guess does it have to be up to me to solve this big mystery?
