Critical oh me

I feel that i am so critical about everything. Whatever that is positive or happy, i will have to think about the unhappy and the negative side of it. It seems to be too extra but it is just to be prepared about the worst. Even people says that i am critical. But i think maybe i am just too tired of my life so, nothing is good or whatever. But no matter how critical i am, i am just prepared for the worst. Like example, i wanted to go pasir ris park for cycling and currently, i am thinking aboout what kind of bad things is going to happen on that day. Well, after thinking about the bad things that are going to happen, i feel so tired and don't feel like going but i know that it is the wrong mindset. I think i am just weird...weird oh me...critical oh me. Haiz...but seeing the people around me just make me go critical. Some people just have craps to say causing others to be in trouble and by doing this, it just make me feel so critical about this person. Even though it is the march school holidays next week but life is not so relax. I better read through physics once more, THOROUGHLY!!! Or else i will just be floating in the air, unable to find a place to land. Got to read through a lot of stuffs to abosrb, to understand. Suddenly, i feel like going to holiday during the march holidays but nowhere to go so let's wait until june holiday. I know there will be homework for all holidays but no matter what, i will definitely complete all homeworks and enjoy my holiday as much as possible :)
