Sadness is always around me

Why do I feel so stress?..........Some of my troubles are caused by my family members like my brother and sister. My sister always tease me or make fun of me and laugh at her own "joke". Then after that she will tell me: Don't cry la! Like that also must cry. I not even crying lor! I will ALWAYS ignore her. Then what about my younger brother? Always 没大没小. Like to quarrel so much. He even threathen to kill my father. He always want to fight and argue... As if he is ALWAYS correct. What about me?.....I don't know lah......I won't make my sister one lor...My brother....sometimes..........Anyway, my family members are not even like my family members lor...I feel that I'm closer to my friends then family members....Even though I always see the same faces in my comfy house, I feel that those are strangers....You won't have the same feeling as me..........cause u don't understand...Hiazzz........nvm....in this world, nobody REALLY understands my feelings. It sometimes seems like crying is my only solution...But always after I cry, I will feel happier and more comfortable. I guess that will be my ONLY solution...
