I'm sorry to hear that things are so tough for you right now. It sounds like you're pretty stressed about a lot of things. Life can be that way sometimes but just remember that this time shall pass and things will settle down. My only recommendation based on what you said relating to your sponsor is to find a new one who is more available. Perhaps get a couple of numbers from folks at your meetings.
As far as the voices go...I'm not sure what exactly they are saying to you. However, I suffered from a lot of self-induced shame caused by a lot of negative self talk. If this is a part of what you are experiencing then I recommend a book by Byron Brown titled Soul Without Shame. I'm not sure if this will be of any help to you but it's all I have to offer.
