You’re angry and blaming her unpleasant circumstances on her poor choices. But perhaps you’re emotional because you’re scared — fearing that you don’t control your own life, so you’re lashing out.
If you can convince yourself that she’s in that position due to her bad decisions, then you can continue believing you have control. But if she ended up in that situation, without choice, then there’s a chance you may also end up there — because without choice, outcomes are beyond your control.
But don’t be afraid, life has gotten you this far, you haven’t been in control this entire time. So let go, accept life’s narrative, and be without fear or frustration.
