Crying at Commercials

Sometimes is hard to identify when you are depressed. I call it my dark path. Its the one you know not to go down to but like the blonde in the horror flick who is standing at the head of the stairs calling to someone below her, you always take the first step even though in your head you can hear someone yelling at you not to do it.
My doctor tells me its called situational depression. It means I am depressed because the place I am in with the Chronic Pain issue. It means if I was not in pain, then I would probably not be depressed. I take a depression medication, and I know I am supposed to be taking them everyday. But every once in a while, I forget for a day or two.
I can tell when it is starting again. First the sad show on television makes a little lump in my throat. Then the shows make me get tears in my eyes, and eventually even commercials make me cry. I know then I am headed down the dark path.
Situational Depression is a hard. You know you should be fine, but you just can't seem to get a smile going. Everyone deals with situational depression at some point. Life happens, you step into a mess and it bothers you. But what happens when the situation doesn't change.
You deal, sometimes its good, mostly its bad, but you deal. I really don't want to deal anymore. I want to just have a nice day, a happy moment and my life back...
