My heart goes out to you Coley. There are no words to say to undo all the sadness and hurt that you felt going through your mother's illness and passing; and if that is not enough, now reading that you too are gravely ill. My God, Coley, I'm so sorry, the news is totally shocking; you must still be in shock and disbelieve about all you are going through.
I don't know what to say, but you shouldn't be alone at a time like this. Please try to talk about your feelings to someone, you must be afraid and feeling very depressed. I find that talking and going for "bereavement counseling", helps tremendously. I started going myself because I needed to talk to someone and get insight to ideas and feelings which I can't understand and now I really need this and can't do without it. Hospice sponsores this service, just ask them for information. We are also here for you, write to us whenever you need to. GOD BLESS YOU FOREVER! I know you will be reunited with your mother in Heaven. You are truly a Good Daughter and a Kind Great Person.
