Take that anger and negative energy and use it on something you absolutely hate doing, i.e., dusting, packing/unpacking, etc. You'll feel much better applying that energy towards something that you've been putting off. Venting to your h won't do a thing, but justify why he left you.
Keep moving forward.
Sit quietly, the answers will reveal themselves when you least expect them to. The past is gone, the present is a gift and you need to focus on today, allow the future to reveal itself when it is ready.
