Glad you are OK. You should check the swing arm and frame. On any bike the swing arm, in particular, often is twisted in these kind of impacts. With some one's help, use 90 degree framing rulers to position the bike perfectly upright. Measure the height to the center of the rear axle on both sides, More than 1/8th inch discrepancy is cause to replace the swing arm with bearings. When you get it off inspect the mounting holes on the frame, and the shocks. Check the height to the upper shock mounts on each side in the same way. This will tell you if the rear sub-frame is twisted.
