Why am I so upset?

Why am I so upset?
Why am I feeling low?
What did I expect? 
What am I to Think?
I am less than nothing!
It is only with You, Lord!
That I am anything at all!
It is only through You, Lord
That I am here and alive!
It is only by Your hand, Lord
That I live and breathe!
It is only by Thy will, Lord
That I write these words!
You, Lord; are my inspiration!
You, Lord; are my guiding light!
You, Lord; are my heart and soul!
It is only for You, Lord
That I am willing to give my all!
