Identifying exactly what went wrong and working to understand and, more importantly, prevent it is key, I think, not just in the sense of ensuring that it doesn't happen again but with regard to being
confident that it won't happen again. Once you've figured out why it happened you can begin to expose yourself to experiences approaching it again, in more controlled ways if necessary, such that you can a) protect yourself from the objective danger (the thing that actually went wrong that led to your accident) and b) overcome the subjective (being scared in all climbing scenarios/all scenarios involving a lower-off, which is understandable but ultimately irrational if you've dealt with a)).
I decked off a route a couple of months back and, while I was lucky enough to be pretty unhurt, then struggled to get back into leading confidently - worrying that bomber placements were going to blow and just generally being irrationally scared of falling. I spent quite a while beating myself up about not being at the level that I felt I should be due to head issues, but eventually got to the point where I realised it was easier just to take a step back and focus on leading easier, well-protected routes, which has worked well in terms of moving back up towards where I was (and enjoying my climbing, rather than shitting myself). Most importantly, though, figuring out what happened - I was rushing to place the gear, which was two nuts, and my belayer was standing quite far out combined to cause unzipping when I fell - has meant that I can work on the fear by putting more thought into gear placements (in particular, putting cams in as first pieces, forcing my belayers to stand close even if it means they might get kicked in the head) and gradually pushing on harder routes.
In your case, gradual exposure to lower-offs may help, most likely with someone you trust nearby (at the anchor with you?) and keeping an eye on you to give you confidence that you're not making any mistakes. Alternatively, (and this is assuming that you're not already something of an all-rounder), mixing up your climbing by trying different disciplines for a while may help; if you're largely a sport/trad climber, experiment with something else for the next few months, be that getting stronger indoors, getting out bouldering, or doing some winter routes, depending on your situation/location. Anything that's comparatively new to you and requires different techniques/mindsets/levels of commitment could well be better for your motivation than feeling the need to get back into something that might well prove quite stressful anyway, will allow your motivation to come back of its own accord in time, and will likely be more practical as the weather become more grim anyway.
Glad to hear that your recovery is going well, at any rate, and good effort on exploring ways of getting back into it!
