Please dont judge me

So I have a dilemma I added my daughter to my health insurance I needed to send some documents to verify her I thought I sent in all the documents but apparently I was missing one and I didnt know well today I get 2 letters in the mail one was saying they were missing a document and the other says they kicked her off and I cant appeal I'm irritated at the while thing once becasue I got both letters the same day and I'm pretty good about checking my mail so I know it wasnt just sitting in the mailbox second I now have no clue what to do to try and get her more health insurance she had an appointment scheduled on the 18th for her 4 month shots there is no way I can afford to pay the entire appointment out of pocket. Anyone know if I can apply for emergency insurance or somthing I live in Texas if that helps at all.

Ugh I just feel so terrible about the entire thing
