Where did my confidence go?

Today I m travelling alone (I usually do) ….. which necessitates a couple of trains and a bus, a premier inn overnight stay and a short early morning plane journey today (only one flight a day now since CoviD ) I ve done this journey many times before, (apart from the overnight stay) however you would think I was going to outer space I am so nervous Having to do some deep breathing exercises? obviously I haven’t been out my town for nearly two years and yes I am two years older but even so everything looks so unfamiliar, so different and inside I m a nervous wreck
Anyway else feel these kind of anxieties
