Glad you're okay. Those episodes can come on so suddenly, sometimes for seemingly no reason. It's true about friends and often family. If they haven't experienced it, I don't think it's easy to understand. At least they were there and supported you without realizing it. Sometimes I take what I call "silent support." I'm not well, but my husband is okay, so I will just sit with him and know that he's there, even if I don't say anything.
