hiding my sadness

I'm depressed of hiding my loneliness, sadness 

I can't do it anymore have to paste that great big smile on my face and show everyone that how ever happy I am but none see how miserable and die I must be inside,

My false smile say a lot about how empty,hollow I have become since you said your final goodbyes.  I can talk to teachers and peers but I don't trust them or you you say I'm not my happy self anymore maybe I'm sick of hiding the smile you don't think is a fake all you say I'm not my chatty 
self when in reality I keep my mouth shut so I don't say anything that is full of anger and rage you think I will let my feelings out just like that but I am strong and in reality I'm just depressed.
