Hi and welcome.
Sounds like you are in a really bad situation, the hospital is a good option if you feel unsafe. I stayed at home during my meds changes - but it did take a while for my meds to get sorted...
I hope your relationship with your partner improves, the guys here will have some great advice for you. We are here for you to vent your anger, your worries and anything else that you can't tell other people. We also have all been through something, even if it is different to what you are going through...
