Hi millionaire (we should talk if true)

I am very, very conflicted about this question, so in the end only you'll know where you want to go from here.

I think it's therapeutic to have a couple of IRL friends who you can be totally open with. Be careful, of course--not because you should be ashamed but because there are plenty of truly messed up people who would gossip about you or otherwise use the info in a negative way; be particularly wary of sharing with work friends--and also be forewarned that even when you think you've identified proper outlets, they may feel uncomfortable discussing the really hard stuff and may change the topic whenever you bring it up--which of course would make them very poor outlets!

As to your mother, that's particularly hard in my book. Depending on your mother's ability to deal with reality and be emotionally available to you, you may run the risk of becoming hurt and disappointed at her response. I'm only extrapolating from my own experience, where I really should have known better than to give her that chance to live up to my low expectations. (I just didn't realize it was possible for her to outdo herself in the departments of denial and emotional distance!)

I'm really happy to hear that you have a loving and supportive spouse. And no, it's not necessary for anyone else to know. It's yours to tell. And then do so not because you feel obligated but because you see an opportunity to take a truly supportive relationship to the next level.

Welcome!
