Hi Nikki,
I am new here too, and I am sure you will find some answers, and some suggestions, and most importantly you will not feel alone anymore !
My boyfriend has been seeing doctors for the past 3 years (vet hospital) and I know he is not out of the woods yet (might never be like he was) this is something we have to accept. But ! my boyfriend is getting much better, and so will your husband ! My boyfriend found help after so many years of wondering, maybe it will go smoother since for your husband it has not been so long !
Hang in there, show him your love and be patient and offer him your shoulders to cry on, cause there will be lots of tears ! He will need you !
Good luck !
