Don't worry about the "should be doings" splitimage; you "should" be taking care of your healing and health. I would suggest though that maybe you talk further with your sponsor, since you do like and respect her and ask her opinion or recommendations of who might be a better fit for you? Thank her too for "letting you know" about her situation/sharing herself and trusting you with such intimate information and practice some of what it sounds like you've learned about being good to the other guy and yourself in how you find another sponsor.
