How to fix a broken touch screen on a iPhone 5?

I have an iPhone and I dropped it and the screen sort of popped out and when I popped it back in the touch screen hasn't worked properly since. It works sort of on certain parts of the screen and it starts doing stuff by itself. Would it just need a new screen? It's hard to do anything on the phone it's self as it don't work.

I seriously don't know what to do anymore?

A month ago my mum was mad at me almost every single day, i was doing all of the chores while my mum watched shows and played games on her iphone. When she gets mad she shouts at me for hours, insulting me in every possible way. And i mean… Her insults are so brutal, like you its not just "you're stupid, you're a b*tch, you're useless, your life has no value", she says those things when she is mad but says other really, not good things, lol. And during that time i was planning to move out, i had a place i could've moved to, but then all of a sudden my mum changes into this person who doesn't get mad everyday, and does cleaning. She's never been a nice person for this long, it's been a month and a bit, so i thought maybe she's starting to change? But I really don't want to get used to her being nice, because usually she just comes back as a mean person after a while, and it hurts even more.
Everything is just so confusing.
is it better for me to move out sooner rather than later? I want to live on my own, but my mum thinks i'm definitely going to stay with her forever.

Why do I feel sleepy and weak? And my temperature changed from cold to hot?

When I was sleeping last night I switched on my AC next to my bed, and first I felt cold then hot… I was wearing long trousers but short sleeved shirt. I'm at school now and its difficult for me to walk I feel so weak! This morning I didn't feel like eating as well. I didn't finish all my breakfast just left a bit of cereal on my bowl. Now I don't feel so good, feeling dizzy a bit, I was using my iPhone before going to bed, got a bit of sore throat and cough too?!

What to do on a 8 hour road trip? - 1

I'm going on a 8 hour road trip on April 2 for Spring Break with my cousin since we will be meeting up with our parents. She is 17 and I'm 15. Her car does have the USB port. I have my iPod Touch 5th Gen with games. IPhone 4S with music, T-Mobile (for phone service), digital camera ( to take pictures), laptop w/ Smokey and the Bandit, Ferris Bueller's Day Off, and American Graffiti. The artists I have on my phone are: Boston, Huey Lewis, Chuck Berry, Jerry Lee Lewis, Little Richard, Jan & Dean, AC/DC, ZZ Top, Lynyrd Skynyrd, Rolling Stones, Kid Rock, Bob Segar, Buddy Holly, Grateful Dead, Bryan Adams, Tom Petty, CCR, The Beach Boys, Joan Jett, Billy Joel, etc. She said I CAN hook it up to the USB port all the way to Palm Springs, CA (we're in the San Francisco Bay). What can we do to kill time? It would just be the 2 of us.
