every sentence you've written is wrong in every aspect, but grammar. sure, you are very sucessfull and independent, so fucking what?
i feel bad for your kids, but wish you all the best, also to your ex-wife/husband, because looking by the way you think about yourself, they had a lot of trouble ;-(
i think in the entire life of my father, summed up, he has never been that prepotent and i'm doing just fine. but i can imagine then what kind of person would i become if he was homeschooling and he would speak that way to me.
maybe take the advantage you've made urself a favour and created a throwaway and rethink your life. you have/had a wife/husband and 3 kids, maybe the problem could also be you and you could work that out and then let the kids have 2 parents(which is very important, 1 is doable also, but not something kids desire or would do them any good).
dunno, maybe go to a psychologist and this doesn't look like something internet people(mostly young that live in sillicon valley) can help. this looks serious and i sincerly wish you the best, just trying to help you. i hope you understand.
wish you the best. you can probably find the job if you dig for it, just do it... but hmm, i would think about everything you wrote there that isn't about the job, like the divorce, like your kids and so on.
hope the reality check was any useful, feel free to send me an e-mail, but as i've said before, a psychologist can help better
