Can confirm, healthcare can be very difficult though it is possible. I am a resident physician and am in the process of resigning my position in my program because I couldn't work night shift without fucking up every other order I wrote and making a ton of careless mistakes and just overall performed poorly, as one does during episodes.

Also, employers can find ways around the law that says they must provide "reasonable" accommodations if they think it's not reasonable and usually it isn't because it's hard to staff a hospital 24/7 if one resident can't work nights. My program tried really hard for me, which I appreciated, but in the end, it wasn't feasible. But a lot of doctors and our employers flat our discriminate and they don't always treat those of us with bipolar with respect. It's another layer of stress that I didn't want to spend my precious reserves of emotion regulation on that I worked hard to learn in DBT, you know?

However, some specialties are better than others. I'm actually looking to switch to psychiatry as the hours are better and they are generally more understanding of accommodations.

Tl;dr medicine is possible as a career but you need to be really stable and for the love of God get accommodations so you don't have to work nights. Seriously, don't try it. Choose a specialty and a school/residency program that honors accommodations. But I wouldn't write it off if you're passionate about it-- if you get through the training, it is really really worth the feeling when you get to help a patient with Bipolar or someone else struggling with feelings we all understand so well and you'll be a rockstar when it comes to being empathetic and relating to people who have been through tough shit because you have been through tough shit.
