I'm sorry for what you are going through is very hard to overcome such a condition by ourselves. But you say your daughter lives with you, so it sounds like she supports you and doesn't want to leave you alone. Why you don't talk to her about your fears? I'm prey sure she will like to help you in any way she possible can. Spend time with her, go out two or three times per week to do something you both love. Don't be afraid to rely on her. This is her time now to take care of you.
Have you though about talking with your doctor? Maybe he knows of a group you can join to? Maybe they are also forums online?. You have us too the people in here, if you need to rant or just say something do it, we will be supportive of you. I wish you the best and I will like to know more of how you are doing in the future time. Just let us know how you feel.
