I'm sorry I couldn't reply to this earlier - I hadn't seen it. I know exactly how you feel about downsizing, we ended up living at my parent's for over a year because we couldn't afford our own place, that was incredibly humbling and very painful - we sold everything that we could bare to part with, I kept some of my bedroom furniture, some of my son's bedroom furniture and a wall cabinet - everything else went.
It's quite nice now to look around our house and be able to feel like it's all a new start, a lot of our things might not be as nice as what we used to have but it doesn't remind me of my 'previous life'.
I've learnt some really valuable lessons and I'm not so attached to my 'stuff'. What I had used to define me - beautiful house at a young age, flash car, nice furniture, wealthy friends. Now it's quite different my stuff doesn't define me and most of the wealthy friends weren't real friends.
I guess, although this will be the first time I've really admitted it, I'm happier - not just happier than when I was when my finances were going down the tubes (that's a given) but happier than when I was 'wealthy'!
So, I hope that this can be a fresh start for you too, and I also hope it doesn't last as long as mine did! It is horrid and you have every right to feel awful about what is happening, but keep it in your mind that it will all get better, much much better.
