You did wonderfully well on your trip away so please don't be hard on yourself, the past 18 months has made us all feel more vunerable. I think isolation, the worry for ourselves, families & friends, the constant negativity in the media has had more impact than we realise. I have mainly driven locally with only a few hour long journeys since the first lockdown, yesterday I made a longish trip on the motorway (been before many times) and at one point I realised I was getting very tense, mainly on the very hilly bits I had to actively force myself to take deep breaths to calm myself. Previously I have driven miles and miles up & down the country, with the family and often on my own five or six hours at a time so like you not sure what it was that made me feel panicky.
