Hi Pebbles,
Oh love, it sounds like you're in a pretty rough place. As Aries mentioned, starting small with a shower might help a lot. Maybe sit outside for a few minutes and grab a little sunshine and fresh air.
While I understand your husband feeling hurt or defeated (loving someone with an addiction isn't always fun), I could never imagine name calling in this situation. That sounds so hurtful and unhelpful. I'm sorry that happened.
Lots of love. Please keep posting and let us know how things are going.
