Family Problem involving a Watch?

Okay... my family celebrated Christmas early and they bought me a watch. It is a $50 watch from Koots. At first I told them I liked it to not hurt their feelings, but I never wanted it. I'm not going to use a watch. So I asked them to return it and keep the money. But they refuse to return the watch. It's not even a fashionable watch! They say that you can't return presents but this watch can CERTAINLY be returned. I want to return this watch at all costs. I am going to threaten to kill myself if they do not return this watch. How do I get them to see reason?!
