strength to let go of pain and prayers for my parents and my sisters mother

my prayer request is for my sister rhonda. she had 7 ulcers in her stomach and when they did the surgery she wound up with a staff infection which caused another surgery and now she found out that the infection is back again. she is cut open from her belly button down and they have to pack inside the incision with gauze to try to get rid of the infection. she may have to have another surgery and is not in the best help. please pray for her.
