IPhone message conversation gone except for one message?

Its not the longest conversation but there are probably 30-50+ messages.
all i have is a text message that they sent me last night. I replied and saw just two hours ago that they read my message at 8 this morning. The rest of the conversation was there. Then i guess my phone started glitching up and it erased all the messages even the latest one that i sent and it only has the message before that.

also when i open my messages it takes longer than usual to open and sometimes exits out. When i open the conversation that got deleted except for one ; the last message they sent it takes like 10 seconds to open.

i feel like this has happened to me before but it recovered… How do i fix it though? I restarted my phone like 10 times and nothing worked.

Added (1). Also whenever i open my messages it goes to the convo that got deleted.a lot

Got a new iphone, how do I transfer my pictures over?

My notes automatically went to mine and I was able just to re-download my apps that I had, and my contacts went over, but my pictures are not going to my new one. My pictures are not downloaded to my itunes either, (like some answers I read said) So how do I do this?

Why does my face look fat/rounder in pictures?

Whenever someone takes a picture of me with either a cellphone camera or regular digital camera I look awful! My face looks thinner in all mirrors I look in to. My mom has a picture of me with my face looking horribly round and huge. It was taken with an iPhone camera. So I don't know if it's the camera or if its me. Pictures make me feel insecure. A lot of times I see pictures of myself I feel like I'm looking at a different person!

What is this iPhone game? Sword game?

I saw a screenshot of this iPhone game and I can't figure out what it is. In the screenshot the background is purple and there's a character jumping from one platform to another with a flaming sword. There are icons for health with hearts and a coin pouch icon and gem icon. In the screenshot I can also see an eye which is part of the background.
If anyone can help, it would be great
