Not showing

I feel so locked up
so alone
I feel like i can't move
In this room so alone
with no one around
does anyone truly care
does anyone truly know how i feel inside
i try and try to hold back
and not show any emotion that i hold in
for i don't want anyone to know
some people notice
and others don't
for i don't talk about what i really need to
i go and talk about other things besides
for i can't express what im feeling deep inside
