you need to forgive yourself... your daughter is young...she will eventually learn to trust that you are going to be ok. the more you cough around her and are not taken to the hospital, the farther away that memory will be taken in her mind. it will just take time. just make sure to give her extra hugs and security each time you do it now so she feels that safety of you. kids are resilient. it will take longer for you to heal from it then her. take care.
