Why am i in such bad mood?

Today, somehow i seem to be in bad mood, like i have mood swing. Maybe because i am too stress up. After chemistry test, i really feel very fed up. Well, i think i lost at least 5 marks. One of it is because i did not study for my chemistry so i cannot remember that but for the other one, i should not have gotten wrong because mr ong told me yesterday how to do that particular question!!! I am so pissed after that and i was trying to solve some equations on my worksheet but it was very noisy around my area. Talking about physics and affecting me in the calculation of the equation. I wanted to ask them to shut up but i knew that they were busy on something serious. That equation only need like 5 minutes but i took 15 minutes!!! WTH!!! Damn pissed after this too. After chemistry test and during chemistry lesson, my blood was boiling. I wanted to shout and kill someone. Today, my emotions seem to be controlling my behaviour and whatever i am doing. This is such a bad bad thing. But nevermind, i just hope that my mood will be better tomorrow and the following days. Today, i found out that the 2 people sitting behind me are genius! During physics lesson, i can't understand a lot of things and i have a lot of doubts. But after the explanations from xin yu and yi kun, i cleared all my doubts!!! I feel so lucky to have smart people sitting behind me!!! WAKAKAKA!!! Today, mr tham went into our class and i walked past him and he told me that my maths journal was atrocious and he said that i must get full marks for tomorrow's test. This is quite pressurising but i will try my best. But i am worried that i cannot achieved it especially with such limited time. I think getting full marks is just to maintain my A in e maths but i really very worried. I am worried that if i get too nervous, i will not be able to do well. Oh gosh...so stressful. Tomorrow, there will also be a maths test and i hope i can do well. 2 maths on one day and i really hope that both of them will not disappoint me especially e maths. I know it may be tough to achieve A1 for my e maths as i failed tremendously for my maths journal. I knew that i was not strong in my maths journal but i did not know that i will fail so badly. Haiz...this is quite disappointing. Well, during CE lesson, miss lee was talking about depression and then, telling us that committing suicide is an offence in singapore and no matter how depressed we are, we should not commit suicide as we should think about the loved ones. Then, xin yu and i started discussing on how can we kill ourselves yet not committing crime. First, we said kidnapping as the police will arrest the kidnapper and in singapore, it is death penalty. Second, we said drug smuggling as drug smuggling is a serious offence in singapore and it is another death penalty. Yeah, we were quite silly to think about all of these but this can be considered as a way to exercise our brains then. Well, today afternoon, there is physics clinic which is actually physics ssp. Well, it was funny when we were about to go into the seminar room. Miss ting forgot her pin number and she tried to think for it while the others tried helping her by asking her "is it your phone number?" "is it your NRIC?" "1234" "4321". They said lots of random numbers to make miss ting to recall the pin number. LOL! Then, we manage to get into the seminar room soon. When we were in the seminar room, jeslyn, judith and i sat together. Miss ting gave everyone worksheets to work on. Judith, jeslyn and i discussed some of the questions and for those we really don't know, we asked miss ting. Jeslyn is very funny. She keeps using correction tape until hers ran out. When she asked judith to lend hers to jeslyn, judith told her to cancel instead but then, jeslyn don't want to and borrow from me instead. LOL! If one ever look at her worksheet, one will realise that there may not be any cancellation but just correction tape. After the whole physics clinic, i realise that the worksheet is like playing around with formulas. Well, i managed to learn something and clear some doubts after asking miss ting. She is definitely better than the trainee. I would rather want miss ting to teach. Next week, there is still physics clinic but due to the movie screening on wednesday, the physics clinic has been postponed to thursday. It is on pressure and i really hope miss ting will re-go through the chapter somehow so that i will not die under the hands of pressure.
