hi A22. Welcome. You do sound tired. I can't imagine how frustrated and fed-up you must be. How old are your children? When was the last time you worked? Although it might be more stressful to return to working, it also brings the reward of independence and the freedom to create the life you want, even if your material standard of living is somewhat lower.
Regardless, you can make your big decisions later. Today you have found SR and there are a lot of stories on this board. From how to keep living with an A to how to live without him, and when we knew, or why we've stayed, or how the challenges were other than what we imagined they would be.
But we all know what it means to be tired and frustrated. Welcome.
