When can i...?

I was brought to earth to see the sufferings and endure them, wasn't i? Sometimes, i will wonder, why am i brought to this earth for. I can't completely say that my life was a total disaster or whatsoever because there are people who are in worse conditions than me. Previously, i post that i am tired of this misery in my life. And now, i must really say, i am really still very tired of it. I have no idea how to get over it. Over 15 years, initially, things seem to be great but as time passes, it is getting worst. I don't know why... Maybe because we humans, are changing. Actually, if it is the changes from young to old is normal but what about changes in adults? Regardless whether am i at home or in school, i just feel that there must be a part in a day that is suffering with misery. Isn't there a day that i can enjoy peace both in school and at home? Just a little peace. I just beg for that. Is that so hard to get? At home, i feel that i am under some kind of ruling... You have not much rights or say. Maybe there is still a little bit or choice making, some says and some rights for some minor minor stuffs. But for some things, just by saying or doing a thing, no matter right or wrong, you may just get yourself into trouble. What kind of life is that? But i don't think i should complain too much. Because compare other families that can be even stricter, i can consider myself with a lot of freedom. At least, i am allowed to do anything as long as i don't get myself into trouble. In school, maybe because as people gets older, they will change. I see myself around people who changed so frequently that sometimes, i feel so distant from them... Somehow, compare to primary school, secondary school seems to be so so much complicated and people, things are just so pressurizing. I don't like stress most of time. I miss the days in primary school. I miss the people who are less complicated in primary school. I miss the food in primary school. I miss the times when we can talk about our own jokes in primary school. I miss the times when i can communicate with every single classmates in primary school. I miss the times when i can be so free even though it may be PSLE in primary school. Oh...i just miss the days when i am in primary school. Those memories, are something that nothing can wash it away from my brain. The people, can never be forgotten. Well, sometimes i hope that time will just stop at primary school, primary 6. The life then, was so much more peaceful, regardless in school or at home. How i hope i can reverse time and stay at primary school and i will be satisfied. Sometimes, it will be great to live in memories, at least memories are mostly happy and they can make you smile. But currently, nothing like primary 6 memories can take place again i think. Currently, i don't smile, i cry. Even when i smile, i don't know if i am doing it for real. I may be smiling on my appearance but in fact, i may be crying for something the others don't know. Although most of the times my face shows how it appears in my heart, sometimes it may not be for real. These will not happen in primary 6. Seriously, when will happiness truthfully regain in my life? When can i stop crying for all the bothering things in my mind. When can i get peace in school and at home? When when when? When can i...?
