Weird Tongue

I have gotten a wierd mark on my tongue, like a bite. I read on the internet and thing it may be "geographic tongue" syndrome.
I don't know, I took a few pictures a few days ago.
It looks like a bite, it felt like it was a bite but I don't remember being bitten or things in that order. Maybe I bited myself while I slept. I am not sure.
Maybe you can tell me what this is ?
I have updated photos of my tongue on imageshack
Here they are:

Hope I didn't get too weird with this (uploading photos)...

Dear Patient
No you did not get weird doing this, actually it was pretty cool seeing a patient taking the initiative to do this.
It does look like a geographic tongue, but the fact is that is localized at the tip of your tongue. It also could be due to trauma, such as tongue biting. But I would recommend that you have it evaluated by an Oral Surgeon.
Thank you

Hi.
The pictures I've taken a few days ago. It got better since then, It's not red anymore but it still looks different from the rest of the tongue.

I am also curios what is the white thing on my tongue. Is that normal ?

Thank you.
