Hello Beesley, welcome to the forum. I'm sorry to hear of your situation. It must seem overwhelming at the moment. Blows like that when we are already struggling with mental health can really send us down eh?
Sometimes just talking things through can help us break down what seems like one huge issue into smaller ones that are easier to deal with one by one. It looks to me like you've got some powerful emotional issues and some practical issues to address.
It's good you are seeing a psychologist. Have a think about their suggestion of antidepressants, they might help you at least get through the worst of the emotional feelings - the anger, hurt, resentment - and help you not spiral down further in your depression. ADs don't have to be forever.
As for the practical issues, my thinking is you should not make any big decisions (like agreeing to sell the house) while you are feeling this way. You need to approach this with a clear head, and some good advice.
Make sure you know your legal position before you do anything! You can get free legal guidance from various organisations - depending on what state you are in you might qualify for legal aid. Do some googling - you don't have to pay an expensive divorce lawyer but you do need legal advice. Then you can discuss the practical matters with your husband from a position of strength.
As for income, he is obliged to pay child support - look at the Child Support information on the Department of Human Services website. Also look at Centrelink's website for information on what benefits you might qualify for.
You're not alone hun, we are here to listen and help you sort through this. Keep talking to us.
