iPhone home button broken, and more problems all at the same time

I have a thick case and glass screen protector that I put on my iPhone 6 the second I got it a month ago. I've dropped it twice since then a week ago and it survived. I didn't drop it today, but the home button randomly stopped working. Now while the phone is locked it lights up every ten seconds with no notifications to justify, but at first it was only every three minutes it lit up for no reason. Also shuts me out of the internet randomly as well. I've always had bad luck with phones. Ideas?
