I’ going to a concert

So me and my boyfriend are going on our first short trip together and as an avoidant person who tends to be very anxious about being seen in a relationship and being in a relationship in general, it could become a very triggering experience. I have had previous OCD themes but the last few years have been very latched to the topics HOCD and ROCD. I just know that spending so much time together could lead to intrusive thoughts about him and our relationship and result in micromanaging and being irritated. Anyone tips on how to enjoy this and not put too much pressure on myself ?

I am going to a country I have never been before and am feeling on edge because I will have to face the Airport, a place that causes a lot of germ related anxiety for me and I will inevitably have to use a public bathroom at some point before I reach my hotel room. This is my biggest fear place-made infinitely worse because I am transgender and there has been a massive increase in transphobia and hate crimes related to trans people using public bathrooms.-I know there isn’t much that will help me with that fear but any general advice on traveling especially in unfamiliar areas would be greatly appreciated!

Any advice for flying longer flights after actively coming out of a ocd episode and now is scared of being anxious on the plane and anxious being somewhere new and how I’ll feel when I’m there and just scared of freaking out and being anxious the whole time and not enjoying myself etc.
