Hi almondjoy! (I just love your handle)
While reading through this thread I think you have had some great suggestions and I have a few of my own.
First of all, good on you for realizing what is happening and trying to find a logical and rational way of doing what you need to do. You health, and that especially includes your mental health, MUST be your first priority.
First before you job, first before your family (And I think it was great that your Mom did all those things for you when you were a kid, but you're not a kid anymore.) But your Mom is not bipolar and as such, she does not fully understand what you are going through-that goes for your husband as well.
I do not believe you are being irrational in any way. Your illness is flashing warning signs at you and it's great that you can see that. Not everyone can. Now it is time for you to listen. I get that you love your job, but you must think of yourself FIRST. What good will it do you if in the long run you end up in the hospital? I was also going to suggest you take a leave of abcense but wonder if two weeks is going to be enough. Only you can make that decision.
I would advise that you DO NOT DISCLOSE! I think that might end up to be a decision that will come round and bite you in the *ss. Given the position you hold, they might surely find a reason to let you go when it will actually be all about your BP. I did to my boss and she spent the next five years using me as her floor mat, and it was the last time I was able to work out in the world. (I did work on the phone after that for eight years, but even then reached a point where I couldn't do it anymore.)
And if you have not noticed, and I am not trying to be dismissive to you in any way-that once you do tell someone, 95% of the time they will never look at you the same way again. In the back of their mind that crazy label is always going to be there.
The symptoms you are having give me grave concern. You have been so strong and have held up for so long but now you must think only of yourself, hon. Maybe you could respond to your Mom, or whomever, with something like this.
"Yes, I have a great job. I love it and appreciate that I have it. But now I am sick and must take care of myself, and my health has to be my first priority. I'm sorry if you do not understand that or agree with me, but if you truly care for me, you will help me. Please do not mention my job again or we might have to stop having conversations for awhile."
That might be difficult for you to say, but right now you have to protect yourself. I am also concerned that you are taking seroquel. There were hundreds of class action suits against the company that makes it because it causes diabetes. I have diabetes because of it. I was on it for ten years and for the last two, I begged my shrink to take me off of it. I finally went to the advocate and never had to see him again and the meds nurse was slowly weaning me off of it. When I started at the VA they put me on effexor and I am doing so much better. I can't tell you what meds to take-only what works for me.
I wish only the best for you and will put you in my prayers that this will be resolved in the way that works best for YOU. Please do not allow this to continue-it souds as if the weight of it is crushing your soul. You are a kind, intelligent and caring person and I know this because of your posts and because you have posted to me and have always been very supportive. Please take care of yourself and stop doubting yourseslf. BP is a cruel master but we can always fight back.
