I don't see any harm in contacting her or her office by phone. If you can talk with her directly, great. If not, perhaps leave a message and see what happens. I know it's scary since there is a chance she may say no, but I think it's worth it since it seems like it's consuming you. I think a phone conversation is a better idea than email since emails can be missed or ignored. However if you find it too hard call, an email is always an option.
