Only you know what you can handle, but I'd be very careful with any of the coasters. My ribs got bruised on BTTMR when my friend slammed into me on a turn. That could be extremely painful for you at this point.
Also, I would think anything with a shoulder harness, like Mission Space. Even though you don't get slammed around, the harness could become tight (even on Green Team side). If you do Stitch, you might want to keep your shoulders high when they lower the restraints so it won't crush into you when they move.
Other than that, be careful and use your best judgement. I hope you still have a great time!
