I got my iPhone 6s Plus today and I hate it. What do i do?

I just got my iPhone 6s Plus and i hate it. Its so annoying to hold and the features arrre stupid. I wish i had bought the Galaxy note 5 it was much much cheaper than iPhone 6s Plus and it has better featuers. I only got iphone 5 cause it was more popular, and i made a stupid mistake. I can't return it cause i bought it on contract for 2years. I hate myself. What do i do? Its too late to do anything! My dad just bought me this phone for my birthday and I'm scared to tell him. What would you do if you were me? I hate iPhones! Ugh! I wish I would of kept my Galaxy s4! Even that's better. What are your opinions?
