Hang in there man - this was going to happen, you give her the proposal, she goes haywire - I went through it too, and we navigated to a mediated agreement. It's emotionally exhausting, but just take one day at a time, tomorrow will be different than today. Hold on tight, it'll be bumpy but you WILL get through it. You can handle this.

I know the feeling of doing things and feeling like you're going through the motions, but keep doing them, or do different things, it will keep your mind occupied and the feeling will pass. Before long you'll realizing that you're living your life a little more, you're engaging more. Keep doing these things for you. It is a process, and you progres BY INCREMENTS.
