What should I do about this family affair?

I'm 19 yrs old and I was recently kicked out of my parents home because I had premarital with my boyfriend of two years. My mother found out this information by pilfering through my laptop, that was needed in order to fix the internet connection because the other computer wasn't working. Now staying with my Granny. Its been 3 weeks. My parents were constantly bringing more of my things over and my granny was telling my mom that she did not have room for all of my things, and she took what wasn't needed back to my parents. My dad called me to ask if I wanted my stuff I said yes, so we arranged that he was to bring my things back to Granny's and that my Aunt was to take it to her house. Two hours later my dad said that he wasn't gonna do what we arranged and that I needed to get my stuff by Friday or its garbage.
