Anxiety and Panic Attacks

I plan on flying to Puerto Rico during Thanksgiving. Haven’t flown for 10yrs. and definitely not after 9-11. I will be w/ my daughter who’s 5yrs. old who’s never flown before and I’m afraid I’ll get an anxiety attack when where up in the air. I have made an appt. w/ my Dr. already to see what he can give me to help me. I want to make sure, what can I take that’ll definitely have me “undercontol”. I’m very afraid.
