In-the-blue moments

I think the thing I hate most about recovery is the down, in-the-blue moments, that leave me feeling like an empty shell and not being able to do anything to feel better. Or at least, not knowing what to do. The thing I've found useful as of late is to run freezing cold water over my wrist-which is where I normally want to cut-until my wrist goes numb. But that only works if I want to cut or burn. If I'm just feeling empty, I don't know how to help that. I try to distract myself, try to feel alive somehow...
