White tongue? can someone tell me what they think of this picture of my tongue?

[Hopes_desires]

I dont think i have thrush, though  im not sure.
My circumvallate papillae seem enlarged and my tongue is white with a coating, i decided to try brushing my tongue for the past few nights and rinsing my mouth with salt water. it just kind of gets rid of most of the coating but i think my tongue is still white underneath. and the texture seems to look weird too lately
my tongue has had a yellow/white coating for maybe over 2 weeks now? its bothering me and i don't know what it is...
if it helps my saliva is pretty gewy i dont know if now im just getting paranoid, but my saliva started to get a little foamy/bubbly and im wondering if that's because im dehydrated...
Someone please give me some advice or help!! I'm worried it could be something more severe?  :(

:) It is not as bad as i thought. Don't worry white coating doesnt go away right away. Do you smoke? Do you eat spicy foods? Use a tongue cleaner twice a day and buy clorhexidine instead of listerine. I'm sure in a week it will decrease significantly.
