It sounds like the indecision is impacting negatively on your life, so at this point any decision seems better than constant indecision. I'm not sure what your decisions are, but can you look at "trialing" options, so if its about moving, then maybe stay somewhere for a long weekend, or if its about work, then trying to visit a few similar workplaces to get a feel for them.

I think you are also grieving the normal process of talking through ideas with someone and letting them shoulder the burden of responsibility. Perhaps if you take the responsibility off yourself and let 'fate' decide somewhat, through flipping a coin or something else that is arbitrary.

Good luck.
