There is a saying I think is relevant to this question "no matter where you go, there you are" so it's important to distinguish if the issues you have are personal, or really have to do with the job. ALL jobs are somewhat stressful and sometimes VERY stressful. Even testing zippers would likely be stressful at times. If one has a good job and is able to keep it and it's "reasonable" to get help working through it, one would be best to explore that option first. With bipolar, we are likely to bring our issues right along with us to another job. But some professions truly are stressful and are best avoided in general with bipolar. If a person cannot make the distinction on if it's the job or their own issues it's best to get a professional opinion or better yet a few professional opinions BEGORE making any big decisions.
