So sorry to hear about what you've gone through Gina. From the little I've read of your posts, it sounds like you have been through such a long ordeal with so much suffering and you've really been brave about it.
I've had a couple of family members who have had colostomies, but not a lot of experience or knowledge about it myself. My brother-in-law did have one for a long time (I don't know how long exactly, but it was months) and he eventually had it reversed.
I will keep you in my prayers Gina. Take care of yourself and may God bless you.
