We all reach that point where there really is no other choice - limbo is not really a choice.
Sending you strength friend. It was pretty harrowing but these Ls know what they're doing. Take their advice - don't discuss any detail with the muppet. Take note of anything he says to you in person or in writing. You never know if you might need it.
I also recommend taking a cent by cent account of what you are spending each day. You never know when you might need that too.
Ask your L for advice about joint funds - I saw a post here about a WS clearing out all accounts.
And lastly - do something for yourself. Take a bath, get a massage - something.
These first steps are the hardest and most agonizing - you'll be running and skipping in no time. Just got to get through this shit part first.
