Unhappiness in life

I constantly feel as though i'm always giving in, trying to make others happy. I have been unhappy. I might vent it out at times with my complaints, whines and mood swings but i'm still unhappy about how things are still the same and happening over and over again. One comes home blowing her nose (without any tissue nor covering her nose) in attempt to show her frustration about how smelly the house is due to the pets, then nagging at me to ask her to clear the pet's house. Just because i am always at home at night, all complaints go to me asking her to do it. Why don't say in her face instead?! She on the other hand would take months for her to be forced to do the house chores. I helped more frequently these months as i'm home more often and would not stand the naggings. I clean and mop the room, buy cat food. Till I feel that i'm being used and taken for granted. Now i know why my father used to say that we take him for granted cos we let him do all the work and not help at all. Two cupboards of clothes are in a huge mess, I will pack it tmr. The rabbit stinks, I will clean it later. Can't wait to shift back to my hall room, leave this house in whatever mess and dirt it will be. I'm too tired, I need time alone for myself without being bothered about how i should care about others and help them. I know that when i start school, i won't be able to eat dinner with father as often as what i can during the holidays. I try my best not to set any meetings with friends for dinners so that i can spend precious time with my father, he's growing old soon. Maybe this is just my character, I would not force others to behave the same way as me. 

I didn't get my hall single room due to the computer balloting though i'm still using my current single room. But oh well, not a big unhappiness so far. i'll try my best to get my single room once august comes. FYP is the biggest unhappiness i guess, so much work and emails keep coming. There's insufficient time for me to learn those skills that i lack off to catch up. Lastly, my bowling sucks :( let down my teammates and lost it. Once the lanes dry up, i'm screwed. wth.
