Hey Ready2Quit (What a depressing moniker you've chosen!)
First... Have you Read DB or DR? These books will help you a GREAT deal with what you're going through right now.
And these boards are a great place to get a variety of different opinions on your sitch.... and to read other people's situations to get a good perspective on how you are NOT alone here.
Don't worry about losing your mind. We all do that once in a while during these times!
Please read DB... Find out about GALing, 180s, goal setting etc. And keep posting here!
