anyone can help me?

I will be very busy within this few days, I need to finish all 4 assignments within this few days, but I haven't started anything yet. Everyone is worrying for their assignment but I'm playing everyday. I know I shouldn't be like this but I can't control myself. Once there are people playing, I will sure join them. I don't even have a schedule for my assignments. I know that I should work harder for the progress test and also assignments, but I won't even think of doing when I'm free. There are many friends and peoples that beside me and will ask me to study and start doing assignments, the reaction I gave them is “I will study or do tomorrow”. Thanks to those who ever advice and pushing me during test and assignments. I will try to change and become good girl, don't play so much and studies must be the first but not playing. I start to sleep late everyday, play with all the friends. Besides that, I love to think a lot when I am alone. I was kept thinking many things but I don’t know what I was thinking. I love to see peoples' action and also reaction, try to know what they are thinking at that time. Once I start thinking or I have nothing to do, straight away I will be very moody. Which will let people thinks that I'm having bad mood, I wasn't having bad mood is just I was thinking a lot. Who can help me with this?? I start to give myself a lot of stress which I will never do it before... I really feel stress but I don't know how to release my stress beside playing...
