I've never been so mad in my life. how to calm down???

1.) my parents never told me that the clothes i got in july(before my bday) was my christmas present along w/ my membership to the local exercise club and snowboard/ski club. They told me today because they were getting mad over money, and i have been asking for 2 yrs now. i don't even care about those things. i wish they had told me before they paid for them. tomorrow is hat day where you bring in 10 dollars to some fund and get to wear a hat and whatever homeroom brings in the most money gets a week of no hw and 10 extra credit pts on the next test. My mom told me if i got my hw done early (which i did) we could go. then my dad came home and they both said here's your last christmas present, and gave me the ugliest snow hat from the dollar store, at first i thought it was a joke so i laughed, then they were like wat r u laughing at.(then again my dad likes to buy things w/ a good price) so i wanted to cry right there and i just went to my room and i'm quietly crying in my closet now. i want to burst out but i cant 'cause they'll get even more mad at me for not being greatful. I've already tried to calm myself down by taking a hot shower, which helped. I usually listen to music, but my dad stepped on my ipod shuffle and it broke. I just want to take a long walk w/ myself and cry the whole time, but its too late. what calms you down? even if i already named it?
