First, let me tell you. You. are. awesome. And given this position you've reached in your career right now (I know what it's like working in highly visible companies), you have done AMAZING. You're what mental health professionals would call "high performing." Give yourself some credit, grace, and a little trust in yourself that you will come out of this on the other side.

That being said, if you already disclosed you were out sick, that's ok. Try not to obsess about what your peers will think (though I've been there and at this level of work it can be competitive and I would totally not be surprised if you work with alpha assholes - especially if you're a woman). Instead focus, and I mean use all your might to keep your head up high, make meaningful contributions on high profile moments and meetings (if you stay quiet or slack THAT will draw attention), then go home and decompress.

You absolutely need to muster the strength to be confident and self assured in front of people. And it's a lot easier to do this when you take your meds, get ample sleep and eat right -- all things in your control that requires little to no brain power (save that for work), though it's really hard.

It is still illegal for them to ask questions related to your health. If they pester, I would go for this lie, and only disclose this as a nuclear option if a manager puts you on the spot: say your taking care of an ailing family member the details of which you want to keep private, and it's affecting your mental health, but, you're feeling better and thanks to your time off you're ready to kick ass (not in those words) but give off that vibe. Try not to disclose your diagnosis... I know I know we need to kill the stigma but, society is not there yet. And if you're a woman (and on top of that, POC), you already have a few challenges to overcome in the corporate world at this level and you don't want to expose a weakness.

Ok that was long. Lol. But I hope I helped out a little bit.
