ImSomething,
I don't think it is a bad thing to tell people a ways before they see any changes. I came out at work a number of months before they saw the real me. (This is partly due to respect for the students I work with.) It worked out well because it gave everyone a chance to get used to the idea of the change before seeing it. It emotionally gave them a buffer period between the old and the new. If you announced now, gave them adjustment time, then started your summer experimentation it might be a little less pressure all at once. It can also take a while to get the word out if you are telling people in person. Just a thought.
Also, once I started making changes, it became intolerable to switch back and forth or take it slow. The more I changed the more I needed to continue. Changing schools could be a good start over time, a fresh start. My thoughts!
