I am sorry that you are feeling so bad. I think that whether or not you need to go to the ER depends on what else you think you might do. Since you are the only one who could have a sense of that, it has to be your decision. I would say don't be alone, and let your husband help you stay safe.

Do you have a T or a doctor who is treating you or monitoring you? You should probably let that person know what is going on, and follow the advice that they give you.

Hang in there and take care of yourself, please. We care about you. I care about you.
