I hear a lot of people say the same thing. It seems to be a little more specific for you (given the whole hospital story). I think it's correct that 9 and 11 are influential numbers in your life, not just ones that "come up often".
For example: I also see 9-11 daily (on clocks, license plates, etc) but these things aren't "personal". My "personal" numbers that come up all the time are
333/9(or 315 which also reduces to 9) ,
5, and
27/9
Better look into what these numbers represent, I really do not know too much. I do think it's interesting that 911 reduces to 11. I think that's the focus IMHO (not at all dismissing the 9).
peace and good night
