i don't have much to offer - except to say stay still and let yourself calm down before you react.
can you afford to get a coach?
sorry to say - but the fact that you didn't resolve things after the first separation - this was inevitable - she didn't do the work and so it was just a matter of time.
about your accident - i've been there and just the long term effects of the whack not he head - is enough of a challenge all by itself. are you getting help for that? that's the first most important thing - it's hard to think straight and the brain gets overwhelmed real fast, so pace yourself and watch for those signs and just take the time to step back and not do or say anything when you are in that state.
as for her demands in the settlement - i don't know your whole sitch - but they sound a bit unfair - maybe you should talk to a L and see what you do have to give her.
focus on taking care of yourself - first. there's no hurry to respond to any of it right away. don't let her pressure you. she'll kick and scream, i'm sure -
i think a little off hand casual shrug from you in response ("well, sorry this has come suddenly, i need time to process and see what is in my best interest" kind of answer) to her pressure will be the best thing right now until you get your feet under you and can think a bit more clearly
i'm sure your old friends and plenty of new ones will come on to help
be strong
