Is this my character problem

I don't understand wht kind of person i am. I can make friends easily bt not a single person is close to me. I tried my best to make a bond bt they went distant from me. Some people told me i have a good character that many of the people like bt then am i the only one who doesn't have any close friend....i am alwayss tensed and scaree where i always need some one to be with me...the one person who i think would be with meeh leaves me and sudden realisation comes that am alone and none of them cares for me. I want a friend the one and only friend who understands amd stays by my side like a shadow....bt reality is shadow cant be visible at nyt. Apparently i am getting confused about everything. Can't even understand people or control my emotions. Want to be quiet and loudness be kept inside bt my face act as a mirror of my heart.....so i can't even hide that.
