Glad you got out
I had a similar situation a few years back, where I completely lost confidence in my ability to get to a summit. Started lots of walks, but turned round disappointed part way through the route. I eventually got my mojo back on Stob Ghabhar, which had been a bit of a thorn in my side for a while.......I can still remember sending MrsR a text from the summit to tell her too
Since then I haven't looked back in terms of getting out, whatever the weather.
I do though have a similar mental block over my final few Munros, despite MrsR very generously encouraging me to get out and get them done. I just cannot muster the enthusiasm to undertake the long drives to any of them (they are all long days unfortunately). I make lots of plans.........then do something easier and/or closer instead.
That said, I have in the last couple of years really enjoyed discovering the "lesser" hills in the form of Grahams or sub 2000s to augment Munros and Corbetts (oh, and the Donalds too). So I still get myself out every weekend I can, even if it is a smaller hill or two or three. I find it rewarding to just "enjoy", rather than chasing targets (even if I will be rightly happy to have those last few "bigguns" done eventually
).
I also used to have a fear of getting lost or heading off a hill in the dark, but logically I realised that even if I was ever "temporarily misplaced" the chances were I would have sufficient daylight to get back to somewhere known and then be safe. I've overcome that fear so much so that now I get myself "temporarily misplaced" on a regular basis and love it
I think for me it was a case of embracing my fears and realising that, unless I was doing something totally reckless, I can only learn from whatever the experience is. As a result, whenever I do get a seed of doubt sprout up in my mind I give myself a good talking to and remind myself of all the much more challenging routes I've enjoyed without mishap.
Now..........I just need to climb me those four small hills.........
