IPhone 5s spazzing out majorly?

Ok so I've had my 5s for just About a year now and it's always been just fine until a few hours ago. It's presses buttons randomly while I'm typin making this very difficult to type, it sends things randomly, it goes into apps randomly, it glitches some way and like combines screens for a split second or something, and it just does a bunch of wacko stuff like that. Iut only does that ( just now it took me to community guidelines?) when I'm tapping or slidin or somewhat touching the screen. Any help? By the way exc use any mistakes as the spazzing makes it hard.

My iPhone isn't updating to the latest iOS update?

Everytime I try to update it goes as far as to agreeing with Terms and Conditions. After I choose Agree, it doesn't do anything, and I've tried resetting and turning my phone on and off but it's not working. Also, everytime I try to update it from my computer it always makes me take it to the Apple Store to fix it.
