I agree with Kitty - not going to hospital due to Thanksgiving is not a good enough excuse. If you had any other disease e.g. cancer, you would not hesitate to go to a hospital if you were critical - Thanksgiving or no thanksgiving.
Why are we so flippant with our mental health and don't look after ourselves in the same manner that we would if it was a physical disease?
I am no doctor, but reading you posts, you really sound like you are in that very dark place and a possible danger to yourself. You are also not taking your meds as prescribed (I understand the side-effects are too much for you), so it all points in the direction that the hospital is the best place for you - your meds can be adjusted, and you are kept dafe.
Maybe speak to the head nurse and either not allow you husband in at all (I'm sure they could make some excuse) or ensure they supervise any visits from your husband.

My boyfriend fo 5 years has emotionally abused and neglected me too; it's taken a lot of heart-ache and hard work to try get him to see this and change. You need your husband's support, so I can udnerstnad the pain you are going through.
Please listen to the advice given here (Even your T agrees with you going to hospital) and keep safe. Check in with us.
