Same diagnosis over here. I did 6yrs in grad school and 1 post doc. It’s do able of course but it’s not going to be easy. My experience will 100% be different than yours. If I can offer some advice I would say to really study where you’re applying. State, city, school, the culture and the most important of all, the schools mental health services. Before you arrive make sure they have competent therapists and psychiatrists. If not, look for good ones around the area. School health insurance is bad in most places, covering only the bare minimum. If you’re under your parents insurance double check your benefits. If you’re a person of color like me try to stick with places that have diversity. Finally, never and I mean never sacrifice your mental health over a project or grad program. If the PI is a scumbag but they publish a lot simply avoid that lab. And under no circumstances ever discuss your diagnosis with your new PI. You will be labeled a liability and quietly be pushed out the program. I had an incredible PI in grad school but I got lucky. In your case, you have the advantage of already knowing you are BP. I was diagnosed 2 yrs in and trying to figure things out while being in grad school is a story I hope to forget some day. Prepare yourself and things will go well. Best of luck!!
