I know how you feel...I've been there too...I wanted to demand my dad's attention...just make sure before you say things in anger....make sure he knows you want his attention...

I said a few things to my dad when I was 16 that I now regret...I know he loves me but the things I said put up a wall in our relationship...and it didn't change much....

but either way I hope you find the anwser you're looking for!!! Good luck!!
