Train anxiety

This probably seems trivial to most people but yesterday I made a train journey on my own for the first time in a very long time. I don’t know why but train travel on my own makes me very anxious ( other transport is fine) so I avoid it. Yesterday I really wanted to go to a special event so made myself get the train from local station into London for it. DD2 met me and we continued journey together so I didn't have to change trains on my own. That’s the next stage for me but I was so relieved I was ok and a little bit proud that I managed it.
