2T I'm so very sorry that your sister is poorly again. Has there been any improvement? I cannot imagine how hard this must be for you. Sending you hugs, and thinking of you.
I don't think your message to your H was a setback, under the circumstances no one should blame you for being human. I understand that you are feeling like running away, who wouldn't be in a weird state if they were in your shoes? I was thinking about that myself the other day, if someone told me six months ago my life and mentality would have changes so dramatically I wouldn't believe them. Yet here we are. Dealing with life before was hard, but my H was not a problem, he was a source of strength. Now we need to adjust and lower our expectations further.
I think your H actually feels like he is supportive, and I know it is so hard, but can you try to take it in a positive way? In his MLC brain he is doing his best I guess?
Again, sending you (((hugs))))
