Why?

I had so many things to say and yet there was nothing I could utter but "OK.". I didn't want to feel down and yet I felt so low I couldn't speak a word. Then, I hated myself after putting down the phone. Have you ever been caught in the same situation? Or, am I the only one who is so sensitive to circumstances that I couldn't accept any reason for anything?
I don't want the sound of the word 'depression'. But is that where I am heading?
Oh, Lord! I pray not!!!
