I have those days too or actually moments. Sometimes I am gung ho about leaving making a plan, feeling confident that its the right thing and what is best for me then later on that same day I feel the opposite because leaving is such a huge step and it would be easier to let things just be. I think for me it is the fear of the turmoil and not the choice itself. In my head I know leaving is probably the right thing to do but it is so hard. Hang in there, keep working on yourself, use the detachment tools, Alanon tools and you will know when and if the time is right to leave.
