I (20f) I'm pretty sure I have anxiety, or at least social anxiety, because when I'm around large crowds it feels like my head was shoved in a fish bowl. Everything becomes muffled and my vision goes wobbly and I can't walk straight without holding onto a wall or other person, I either walk at angles or wobble like I'm drunk and have actually fallen over into walls a couple times. I do not want to go through an airport alone for the first time not knowing what Im doing while I'm also in that nightmare haze. I have flown commercial with family years ago before and remember checking in at some sort of desk and a separate computer thingy, but this time I only have a carry on, no luggage. If I already have my ticket do I need to check in anywhere besides the actual gate/terminal/tsa?

 I also ended up staying awake until 3am practicing unpacking and repacking my bag cause im afraid im going to be too slow going through TSA. Do I have to take EVERYTHING out individually for the bins? or is stuff in clear plastic zip lock ok if its visible. ( like clothes and charging cords) ?And are portable chargers allowed? and snacks, I remember my mom saying foil packaging isn't allowed and I have to unwrap snacks and put them in clear baggies.

 Im flying out of San Diego
