You have a lot of things going on and it might help to separate them out into chunks. in this way, it might not seem so unmanageable becaue you can look at each thing separately. You can prioritize your issues and deal with them as you can. I know that when I am overwhelmed and I look at the whole package at once I become paralyzed becaue it is toooo much to deal with.
I think you might want to deal with your medication issue first because it has such a huge impact on how you feel and how well you will be able to deal with your other issues. I am not an expert, but I know that stopping meds all at once will have an adverse effect. Some doctors will see patients on an emergency basis. But if your pdoc wont see you and you feel you are in danger, then by all means go the ER. You can also call a hot line if you need to talk.
If your T has said he is not leaving you, why are you worried about not seeing him? Did I misread something?
Take care, and please reach out if you need to.
