Hi Sirensong, I'm sorry you're finding things so difficult right now.
Good move getting the physical check up, always worth ruling out any physical causes, but depression can certainly affect your libido, and the attraction you feel towards others which you mentioned had faded in terms of your husband. So depression is definitely a good point to address too.
[Although just a thought..........if you're taking meds for the depression can you make sure with your doctor that it isn't the side effects of the meds causing or contributing to the problem too. Some meds can cause/add to the types of problems you're having........so worth discussing the pros and cons of changing them if so]
And the depression..............any extra help you could get with that e.g. seeing a T...........??
Or even posting more on here!!
And maybe couples counseling could help too, could help your husband with the feelings of rejection and help him better understand how you're feeling, maybe leading to him being more sensitive/supportive towards you in relation to to the problems you're having, help you both work through them???
Try not to see the problem as wholly your problem, apart from it not being your fault (!!!), you're a couple, and something for you both to work with/through, there may well be things he can do as well to make the situation easier/better.
And........in terms of re-establishing some of the intimacy it might help to look or post in the Sexual and Gender issues forum. I know there have been issues similar to yours posted in the past and some great advice given.
Best wishes
Alison
