I'm all alone in this

Well..I don't what to say about this but my mind always lingers about things that are sometimes beyond my capabilities..I'm a perfectionist..I want to get things right if possible...sometimes my mind came across this question,“have I able to meet the expectations for the day?"well not all days I would be able to answer that question but when I couldn't,I would keep quiet and then tears would start rolling down my cheeks...I also asked whether have I pleased other people or have I made them despise me...I'm scared to hurt other people feelings but sometimes people have to be taught that way...I wouldn't say myself a happy person even though when you see me a outside,I'm a very lively person but I would try to hide my sadness cause I don't want others to worry about me..but suffering all the pain alone is quite painful..even sometimes I have to cry all by myself sometimes I try to find a friend whom I could talk to about all my problems but I'm not able to tell everything...sometimes I wonder why life has to be complicated with all these feelings,emotions and all....I would say that my life is full of existing questions that are not yet answered and all of them I must find them out through facing challenges in life...I wished I could talk to someone right now...
