Family members keep stipulating what I need to do and a good friend of the person I care for phoned me today and has told me to (temp leave my husband) and go live with this person full - time. I am not sure If I am emotionally strong enough as they can get a little emotionally abusive.
I doubt this will help but I think you need to tell the people who have decided what you should do to be quiet unless they are willing to do it for you.

Telling you to leave your DH who I assume is supportive of you to live with someone emotionally abusive while you are already struggling is not acceptable.

Have you had treatment for depression? You do need to take care of yourself and maybe it is time to ask the others, regardless of whether they work or live away, what they are willing to do to help. If someone is willing to cover you for a couple of weeks, that may help.
