P.M.
I hope you will NOT to think of your little guy's feelings as "wrong." He really doesn't choose them, any more than you "choose" to feel upset when his behavior puzzles you. Anger and frustration are natural, and completely legitimate. If you discourage them, the feelings won't go away, they'll just go underground and emerge in some other way.
If you stand in his shoes and consider life from his angle, you'll be staggered by all the frustrating, controlling, maddening and discouraging situations for a new little person with little choice and limited skills or language. From there, you might find creative ways to reduce as many of those frustrations as possible. This in turn should reduce your son's negative strategies to deal with his own frustration. He needs lots of empathy and guidance to help him navigate the next couple of years, which are indeed challenging ones for both child and parent.
One of the best guides in accomplishing compassionate communication is the book How to Talk So Kids Will Listen, and Listen So Kids Will Talk. Read part of this really practical approach here: http://www.amazon.com/How-Talk-Kids-Will-Listen/dp/038081....
One other thought: Inhaled chemicals are a big problem for me and for a growing number of children. I've been in group testing situations where a child goes from calmly coloring to raging or weeping, mere minutes after being exposed to some of the common chemicals in our homes. In addition to breathing problems and sleep disturbances, I find that I also experience mood swings when I breathe other people's colognes or can't avoid the air "freshener" in a public restroom. You might look into reducing the use of scented products around your son and see whether he manages his moods better. Fabric softeners, scented candles, new carpeting, bedding and clothing, dry-cleaned items, newly-photocopied papers, etc. – anything you can do to reduce the chemical load may help. And even if this doesn't improve his mood, he will probably be healthier over time.
