I dont understand

I don't understand
What's going on inside
I trusted you
You held me safe
But now i cant say
Why I am this way
I pulled away and won't let you in

I tell you I am ok
But I am dying inside
I say that I am not doing anything Wrong
You believe

Why can't I be open once again
Why can't I believe
Why can't I tell you whats going on
I don't even know why I am this way

Someone help me
Please come my way
Someone tell me I will be ok
