What should I do?where should I go after my foundation in science?what course should I choose after this?i really what I should i do?i feel very confuse now..I dunno what should I do to improve my result?i really scared that my result will be bad until my final ?actually I really feel scare n worry ,but I should try to act as very happy in front of others..I noe that I already changed since I enter this university..this is the thing I nvr do before.last time I will just show my real feeling to others,now I also not dare to tell my parents that actually I feel very confuse now..
Like a person is not a easy thing .how hurt is he looks at your as a stranger and actually you two are classmates..how sad are you when you see he can talk happily with your others classmate except you..so in this world better dun wan any feeling..a person without any feeling will life better ,I guess..
