A little bit upset

Well, i realise that life will not be just fulled with cheerful and happy, sometimes it'll come with a little bit upset too. When I face this everytime, I used to hide it deeply inside my heart and pretend to be happy as usual in front of people. I would not simply express my feeling to anyone, including my dearest family and him. I've to solve it myself, showing in my face or action just manage to get more people's comfort perhaps but nothing gotta help with the problem existed. Though there's something troublesome, I still choose to keep it as secret. I found I have nobody to share with everytime I face the troubles, yet I'd rather share it with a stranger if I could. Maybe many will say that I should share with him, but I can guess what his responce after I told him. I always try to bear with it, I'm yet still trying to get more improvement but something did hurt me thoroughly today. Yeah, I'm unhappy...but still gotta force myself to smile when there's somebody else in front of me. I'm so struggling.
