Yes, it wasn't that I wanted it this way

Yesterday, I had myself an exceptionally rough day. With having the two children in the morning, by myself, while the wife was at work and feeling paranoid and having disorganized thoughts--but nay, once I headed that off at the pass, I wasn't finished yet. Once she got home, I went off onto some overstimulated jaunts in the prison of my mind. Then it was time to carve pumpkins, and yet again, I was assaulted by the innate rants of my psychotic mind. In and out of bed at this point, I managed to fend off the onslaught until it was time for a restful sleep. Even in slumber, though, my "off switch" wouldn't be tapered. Tossing around just beneath the surface, my mind wouldn't let me be at peace, until the morning, when it all went away. Thankfully, the following day (that being today), I went on beautifully with a wonderful day when I was able to complete all tasks at hand, as well as be outside with my children, and visit my dad at his home. The Alpha, the Tau and the Omega. Just remember, there is always a tomorrow.

Children's Self Portrait

My son--who's father has schizophrenia,  has been making self-deprecating remarks about himself as a pattern that I've seen over the past year.  He is a six year old in first grade doing really well in school and by all accounts is a healthy, smart, talented and promising young lad. The only problem is that I think he has unfortunately started to walk in his father's footsteps and has, by his mother and my observations, begun to show signs of developing mental illness later in life.
Part of me wants to think he is joking--trying to get a rise out of us, partly due to his childish expression on his face when he is asserting these unusual-for-a-six-year-old-remarks of negativity about himself. Another part of me wants to seek help for him in the form of bringing him along to my psychiatrist's appointment. 
Will it all work out for the best in the end? Or would it be best if I acted upon my instincts and sought professional help for my son?
