um... stress!

  Recently, I am having extreme stress. I don't have a way to handle, and relieve stress. The resource of stress is my academy which is near the my school. Actually, I have had little dissatisfaction with its manager's management. Today, however, I was disappointed last Monday. Last Monday, our students finished class at 11:30 because of seminar which was about 21st century new learning skill(? I am not sure about what I wrote..) BUT, Thanks to someone, (I don't know exact name of him or her maybe Dr. Santos?) we had to attend to that seminar so I went to academy like usual. There, I saw messi and @@ teacher having class 4~5 when I was supposed to have a class. I asked manager why they are having class instead of me. She said 'I forgot.' even if my brother told her 'my brother will come here like before because he will attend to seminar.' so I should wait an hour and was late an hour of my day plan....
BUT I don't mean that messi is bad and my academy is bad. Just way of management...
I got stress today as well but I don't want to mention about it. 
  I don't have way to handle and relieve my stress. Usually I used to handle my stress by playing soccer and playing the guitar although I am really not good at playing it because it is fun and interesting! I can't handle my stress by soccer because recently, my kicking became totally, definitely, absolutely, suck.. I think the reason is that because I didn't play soccer for a while. I think My brother is better than me at least now. so whenever I play soccer with my soccer club and my brother, I get stress, not relieve stress. I am going to practice it during the easter holy week.(Everyday..) For playing the guitar, the circumstance is not good. 4th string has severed 2 weeks ago or more than that so I am not able to play the guitar..

I am looking for what can relieve my school.
