Welcome to the Beyond Blue forums, I'm sorry to hear how you are feeling.
If you don't mind me asking, has you husband said that this is how he feels, that he doesn't love you anymore? Perhaps he is suffering from something?
I am not a doctor but I think I know what you can do next; keep loving being a mum. Don't stop loving, you are a natural at it and if you can keep your heart in this place, loving your son, you can make the the rest happen. Because you love your son and because you have the ability to love you can go on the journey to find where you will live in the next few months, you have the choice to go on the journey with love in your heart or fear, you choose love. In terms of a accommodation, do you have family or friends that could help? There will be other options available.
Love to you and your family.
