Stick with it, old mate - it's vital to make it more of a habit to go out than to stay in.
I know you have off-road bikes, so the opportunity to stay traffic-free will have been explored. I tend to avoid riding at weekends due to the increase in people with a decrease in patience and consideration post-Covid, who are doing the weekly shop/taking junior to xyz/driving the dog for a walk etc.
I find that Fridays tend to be the quietest due to the volume of people now choosing to "work from home" on Fridays, and that weekdays between 09:00 and 10:00 (after most have got to work) and 17:00 to 18:30 (home from work/before going out) have reduced traffic, but realise weekday riding is not an option for everyone.
The more you go out, the more confident you'll get in you and other road users.
Above all, avoid school run traffic.
Thanks chap - appreciate your encouragement
Unfortunately I'm coming at it from the other end.. I used to be a lot more confident riding on the roads but it seems this is diminishing thanks to a combination of both an increase in my general anxiety and unpleasant interactions / conflict with drivers; be that as a pedestrian, cyclist or driver.
I grew up loving, and generally being pretty involved with cars; however I'm increasingly coming to hate them for what they represent, the damage they cause and the way they serve to amplify the worst traits of some.
The problem with traffic is made worse with where I'm living currently as it's pretty rural and affluent; meaning an amount of self-entitled muppets who aren't used to accommodating anyone but themselves; especially cyclists.
I don't often let the anxiety stop me per se, however it does contribute as another of those low-level factors that makes me think "meh, maybe I won't bother" on some occasions.
I try to ride out of rush hour if I can and off road where possible, however proper off-road is difficult in the winter as I'm not used to / can't abide washing the MTB literally every time I go out because I've come back with half the countryside stuck to it.
I'm lucky in that my commute is pretty much exclusively tow paths and Oxford city centre (where the traffic is slower and much more cycle-friendly), while my semi-regular shop (as per my last post) can be made on country roads and maybe 20% off road; however of course it only takes one inattentive / aggressive / entitled idiot to write you off.
With increasing age the underlying urge only grows to just get as far away from people as possible..
