Neighbors?!

So I didn’t really know where to post this and I really wanted the advice of women but I’m 15 and I have been best friends with my neighbors for 10 years we basically grew up together. Their parents who are super strict are moving them to Kentucky from Illinois for no reason! Their dad has cancer and all of their doctors family and friends are here in Illinois! Y’all It frustrates me to no avail that I can’t even talk to their parents without almost yelling at them! Does anyone have any advice on what I should do to help myself come to the realization that I might not ever see them again!

EDIT: thanks y’all that actually helps me so much❤️
