Trying to get motivated

Options
I am 43 years old I sit in an office all day long (on a stability ball), I am a married and I have a 7year old and I really can't seem to find the energy or time to work out and then when I do start working out I end up with a stuffy nose and sore throat. I mean really you have got to be kidding me.
I am new to the site. But not to weight loss and weight gain and loss and gain and loss and gain... again and again over and over.
I have been around this mountain so many times I lean to one side. I am looking for motivation. I know what to do I just lack the energy and motivation. My doctor says just stop eating the twinkie... (I don't even like twinkies) and he says my thyroid is fine. So I guess I can't blame it on anything but my lack of movement. Looking for some friends to help hold me accountable.
