Losing a significant person

I received news late last night that a dear woman to me, Mom Taylor, will be passing away in a matter of days more than likely.  She has spent the last month in ICU at Mayo Clinic in Jacksonville, FL.  She was initially admitted because of an infection preventing her from receiving blood units to help with her cancer she's been fighting for about 8? years.  Turned out that it was E.Coli. Well, I guess the cancer kicked her while she was down... and it's 90-100% in her bone marrow, all over her body, there's not anything more the doctors can do for her. :(  They took her off her feeding tub last night, and today will be removing the ventilator and letting nature run it's course.  There is so much more I want to write on this, and will when I have more time.  I am at work trying to find some sort of concentration right now.  I'm beside myself, feel like throwing up, completely drained and saddened.  My heart is completely broken, in no way it ever has before.  This is the first significant person in my life that I will have lost.  I have certainly had family members pass away, but my relationships with them weren't anything as close as the relationship I had with Mom Taylor.  She was Mom Taylor because she was exactly like a mom to me and saw me through more than anyone could have asked for at times.  She was a best friend, sister and mother figure all in one.  I miss her so much already for the past year... being away from Jacksonville and all... and now.  Now I won't even be able to tell her ever so often that I miss her and love her.  I don't even know.  My heart bleeds even more for her family.  Her husband, who seems to already be lost, and her two sons, Jordan and Josuah.  She was an amazing woman, wife and mother... this is going to be terribly hard for them.  Not to discount how hard the past month has already been.   I'm just beyond any words on how I'm feeling right now about this... and will definitely sit down to write out this past month with her..  I love that woman, always will.  I am sooo saddened I won't be able to laugh with her again.  :(
