Happiest Weekend of My Life

So the best weekend of my life is over.  I went camping at Samuel P. Taylor Park with my family and cousins and it was great.  We had smores at the night and we had delicious dinner and breakfasts.  Everyone was so happy, my mom and dad weren't fighting and my sister was so sweet and amazing.  Then I had to come home yesterday and my parents started to fight and my sister was acting out again.  What happened to everyone?  They were so perfect during the weekend and then when we got home they weren't.  I sat in my room wanting to go back to the beginning of the weekend and wanting it to last forever.  Now it's another stupid week in school.  I have so much homework and I have a project soon due and the rough stuff is due thursday.  My group had nothing and we are going to shoot tomorrow and now my mom is really mad at me because I am going to have to miss basketball open gym because I feel like school is more important if I want to get good grades.  Honestly I just want to go back to that happy weekend and then I feel like everything would be some much better.
