You might try hitting a high school parking lot, or something similar, on the weekends. Should be empty, and probably has some obstacles like light poles or medians to practice turning safely.
Work on some basics. Get a good feel for the bike and how it reacts when there is no danger, and it will come more naturally when there is.
I found, when I started out riding, that slow was my enemy. I could buzz down the highway at 60mph without thinking, but dumped my bike turning into a parking space - the MSF will teach you slow riding techniques, plus you can dump some P.O.S. 250 and not worry about your own bike. (not 'dis'ing a 250... but the MSF bikes are crap at any displacement

Don't think of it as a stop light. Think of it as a chance-to-show-off light.
