It's hard to not have acceptance and support from those you want it from the most, I know this well. When the depression and anxiety drain and overwhelm you to begin with, having to fight on one more front does make things seem even more impossible to overcome. It sounds like you are doing well in getting the help you need, and doing what you should to help yourself. Just keep reminding yourself that your focus needs to be on what is right for you, for right now, and that you shouldn't let him, or anyone else, interfere with what you are doing. As the others have said, if he is hurting you by his words and actions, then do what you must to limit his interaction with you, even if this means cutting him out of knowing what you are doing.
