I’m not sure if this will help you, but it helps me so I wanted to share: How early do you start packing? You may want to lay out your bags and begin packing your things (that you don’t currently need). Make a list of essentials that you don’t want to forget (wipes, extra masks, your distraction items for the plane etc). When you think of something that you want to pack, pop it in the appropriate bag, don’t worry about organizing just yet but you will know it’s in there so as not to be forgotten! When you feel anxious go to your bags, look at the things you’ve got in there to assure your mind that “you are prepared” this gives me a reassuring feeling of control (that may sound silly to some people that don’t deal with anxiety or excessive worry). But, for example I might wake up and think “what if it rains!!!!” But I can glance over at my bag and realize that my ponchos and my umbrellas are in there. This relaxes me. Umbrellas are also good for ensuring ppl keep their distance from you, since you mentioned something related and many people use for shade so you could have it all the time. If you wake up worried about the plane, you can glance at your bag knowing that you have “your gear”, you are prepared, you are in control, it’s going to be fine!
Edited: I wanted to add that yes I did see OP has 60 days to go and yes I do start packing that far out bc it engages my mind, making lists and adding to my bags is my pre trip project of sorts.
