Genesis,
You have to know that this is not your fault. You have a disease and are doing the best that you can. Depression and other mental illness make us feel sad, tired, and want to isolate ourselves from others. How is that your fault? You did not ask for this to happen to you?
I know that it is difficult, but you cannot start to help yourself without first stop being so hard on yourself. Do the best that you can do and that is all that can be done.
It does not sound like your husband is very supportive and for that I am sorry. I am sorry that I do not have any advice on how to handle the situation with him understanding. Just know that we are here to try to help you sort through all this stuff.

Stay strong,
Jessica
