Why is my data being used so fast? (iphone 5 AT&T)?

Before when i had JUST got my iphone 3gs i was going through data very fast but it was because it was my first smart phone and there WAS so much new stuff for me to play with so my mom upgraded my data allowance and i had never gone over since ( i had the 3gs for a good 2 1/2 years) but i recently got an iphone 5 ( its almost a year old) and at first i wasn't going over but now i go over EVERY freaking month always right at the end of the month but now i just got an text saying i've used 65% of my data and its only the 12th! I swear to god i'm not even on my phone all that much besides briefly checking my email or instagram/tumblr/vine i face time OCCASIONALLY like i seriously can count on one hand how many times i've facetimed could there be something else going on? I'm So annoyed!

Added (1). Also we've had AT&T for YEARS (like 6 plus years) and i remember having unlimited data all my friends were grandfathered in and got to keep there unlimited data plan by my mom and i never were? Can we still get that?

Added (2). I do call long distance a lot from WA to CA but i have long distance calling on my plan? If that helps?

so the fletching thing didn't work it was already on manual.

Is she testing me to see if I've changed?

My ex after a year texted me we hungout. We had sex and talked and made up all was well. She said shed go to dinner with me monday. Sunday night she told me she might have to work late like my old self I flipped out. She said I haven't changed. A week went by and she texted me and said it doesn't make me wanna see you or think things will be different when you act like that. I apologized. 2 days went by. Yesterday I texted her a nice note basically asking for a chance to prove to her. She read it and didn't respond. 2pm today she texted me and said sorry I didn't read I fell asleep but I know she did read it because she has an iphone. I said don't worry what did you think. She said I'm not ready right now to decide after last week. I said give me a chance spend time with me I will prove it to you. She said i don't know Ill text you later I'm not even out until 2 am. My question is what should I do is she testing me to see I get mad when she doesn't respond or hangout should I just play it cool.

Why have I paid for 8gb but only got 6?

I've recently bought an iPhone 4 with 8gb but when I synced it on iTunes it says I only actually have 6gb. This is with "other" which I know how to reduce. Also on my iPhone itself on settings it says I only have 6gb. This memory is very valuable because I only have 8gb and if I'm honest I think I should have bought at least 16gb. Can you help me by answering with an easy answer baring in mind I'm only 15 and you'll probably confuse me?

What's going on with my iPhone? - 1

Ok so yesterday I went to go text someone and instead of names of my contacts in my recent conversations there was their numbers. I have no idea why this is happening. I can't tell one conversation apart from another. How can I fix this? What's causing this?
