MY IPHONE 5C PICTURES WON't DELETE OR SEND?

So i have a white iphone 5c, updated to 9.2.1 or whatever recent update on IOS and well i have 8 gigabytes but it says i only have 5? But thats besides the point! Anyways i usually always run out of space like, i can't take pics all the time without deleting some. Well i somehow got up to 1003 photos on my camera roll and so i went to go delete the ones i didn't need (i usually delete the pics i don't need after i screenshot them and done using them) but i forgot to the past couple days well everytime i go to delete them they disappear for a second and then it freezes and won't let me out of the "select" to delete thing. And then if i exit out and check, they are still there and didn't even erase. And i even tried deleting each of them individually like clicking the picture then the trash can but then they d just reappear instead of erasing! And then i tried to send a picture on imessage and kik and they would not send, the imessage app would just freeze and kik they just won't. Has this happened to anyone else? And yes i've tried turning my phone on and off, and resetting it and all that good stuff but nothings working.

Is the iPhone 6 worth the upgrade?

I have the iPhone 5s with no working Touch ID sensor, I feel like it glitches with the battery, and is a bit small, so it makes it harder to type sometimes. It's in okay condition, scuffs and scratches here and there. But should I upgrade to the iPhone 6? I don't want to buy it from my carrier since the color I've been eyeing is more expensive and only comes with 128GB which I don't need, plus I think I can get a better deal from eBay or Amazon- what do you think?

I have a strange desire to eat my iPhone

I see people with iPhones and I have this desire to take it away from people and bite into one,

I just bought one and I have this urging impulse to bite into mine,

What should I do?

If I buy the plastic casing on the iphone 5c can I put it onto my iphone 5s?

I'm kinda getting bored of the way that my iphone 5s feels, if that makes sense? Anyway, I wanted to have something like the iphone 5c, without having to actually but the phone, and still get to have touch id, so I was thinking would it be possible for me to buy the plastic casing and put it ontp my 5s? Perhaps if I took the back of it off?
