She cares about you or she would not have done that. Now you may have a long ways to go to repair and rebuild a relationship, but take heart in that she was at the hospital in 10 min. This means that deep down she cares about you and this means you have a chance. You just need to recognize that you have a long ways to go. You did the right thing by just saying thanks and leaving it at that.
Sounds like you two can be friends and that is a starting point you can build on. Remember non-demanding persistent love from someone who loves himself is hard to resist.
