Sorry about your falls.
I think part of your problem is that you are not driving your bike like a car. You should look up vehicular cycling and learn the concepts.
I say this based on this description.

This time there was a car waiting to make a right turn (legal on a red light here) and I noticed that, again, this driver did NOT see me coming to the intersection and was preparing to turn right.
First, the flashing WALK light is NOT for you* and you should not be crossing in a crosswalk. You should either be in the lane or on an improved shoulder.
Secondly, you NEVER should put yourself on the right side of a driver in the right lane unless all the traffic is stopped. The "right hook" is so common that is has the name "right hook." You should have ridden behind that vehicle and then you would have made it safely through the intersection with no stopping required at all.
You could have probably avoided the first fall too by anticipating and avoiding rather than stopping.
* other than as a indicator that the red light is getting stale.
