What do i do to repair my iphone?

So i smashed the screen of my iphone6, and there are a bunch of strange colors and lights of the screen. It's also unresponsive. If i get my screen repaired, will that also automatically fix the other issues, or do i have to get them repaired separately?

My iphone 6 turned off and won't turn back on?

I haven't run out of charge, i had plenty, i was scrolling through instagram and the screen just went black. It felt really hot to touch so i set it aside and waited for it to cool down. Once it had i tried holding down the lock and home button, it went warm again but aside from that nothing happened. I've tried connecting it to my laptop but that doesn't do anything. Its a fairly new phone as my previous one shattered. Any ideas?

Can my parents really see everything and everyone I talk to online?

Okay so recently my mom comes up to me and says "You're dad knows web specialist, they'll find out who you're talking too and what you're doing on video games or the internet and ect…" (Context, they don't want me talking to my boyfriend anymore cuz he's not our religion) so like… Can they actually figure out if I'm talking to him on Snapchat or discord? Or video games like Overwatch and steam? Like on my laptop or IPhone?
