hang in there man.
I know a lot of people including myself that have gone through the same ordeal
I've had such a bad season so far.
shot one last night and the arrow went through it and I could never find blood or anything.
looked for hours and hours with nothing to show for it but an arrow with hair and blood on it.

I shot and missed four times before that too.

hang in there.
it's only your first year.
remember your first year with a gun?
I do and it was just a big learning experince where i didn't take one shot and only saw a handfull of deer.
now I see fifty somthing deer a season and nother gets by me when i choose to shoot.

The biggest thing i've learned this year was how much more patience you need with a bow compaired to a gun.
