Thank you for your responses. I really appreciate it. No, I'm not on medication at this time, although I probably should be. I'm not in a crisis, thankfully. My family and friends are good about distracting me and helping me regain some perspective.

We were given even sadder news about my sister in law. There is nothing more doctors can do for her and she was sent home today with hospice care. Doctors say that it will likely only be a few days before she passes . She was awake and aware and is okay with dying, which made my husband feel somewhat better about letting her go, which in turn relieves some of my anxiety.
