Keeping Communication Open

I usually think I have a great job. I have much freedom to do what I want and I feel like I do things that improve people's lives. I like the fact that I can legitimately drive around Northern California to do my job. If I didn't drive around so much I wouldn't be doing my job.
On the other hand, sometimes, like tonight, I really don't like my job. I don't feel that I am important and everything I do is wrong. I feel that I am not appreciated by my bosses and they ignore me  because I don't make a contribution to the companies mission.
Why do I have these opposite feelings? I think it all comes down to open communication. I go out of my way to make sure everyone knows what I do and try to get feedback as often as I can. I have developed a system using Microsoft Outlook to keep everyone informed and participating. My supervisors only communicate with me when I am in trouble or if they need something. What that causes is anxiety and worry about how I am doing.
I always wondered why the boss has a morning meeting and we just review what we are going to do during the day. We usually do the same thing every day so the meetings seem redundant. I even did the same thing when I was a Company Commander in the Army. Now I realize that routine is important. It reduces the anxiety and increases the contentment in an organization. I will continue keeping the communication open and force more feedback from my bosses (after I figure out who really is my boss).
