I understand your fears. I suffer from anxiety, but I try to learn as much as I can about any new place I go, including airports. I will watch a
youtube video about the airport I am traveling to, as well as looking at the airports website.

It helps me to get to the airport early. My family isn't always happy about that, but solo travel is all about your wants & needs. Also, if you can travel with just carry-on luggage, you won't have to deal with having to check your bag at MCO (that line can be brutal)
Depending on your budget, you can hire a car service that will meet you inside by bagggage claim.
