I'm sure it's quite frustrating for you, but try to remember that things do often times happen for a reason or turn out differently than we hoped with blessings in the end. I'm thinking that the lawyer just wasn't the right one to work for you. You used him before for advice and whatnot, but I guess he was just meant to be a stepping stone for you.
As for your ah - well, you knew that he was "crazy" already. I guess maybe now you're just seeing it a little more clearly. I applaud you for not trying to have a full scale conversation with him. I'm sure you know how that would have turned out and it's really just not worth effort.
While it seems really crappy right now, I have a feeling that you're just going to come out of this mess a whole lot stronger than you went in. Always seemed to me that things always get worse before they get better, unfortunately.
Hang in there! We're all rooting for you and you are not alone!
