having a hard time and I need encouragement and support

I am 21 years old, an only child and my mother and step dad are all I have really..i've been striveing to lose weight for myself but also because my mom has cancer and i want to lower my risk factors to hopefully lower my risk of one day getting cancer as well, so I am trying to get healthier.

My mom has been between the hospital and rehab facility not home the past 2 months and a week. On January 1st of this year we found out she had essentially two different cancers large masses on her overies and a mass in her rectum. Shortly after that she had surgery to remove the masses on her overies, gave her a full hystarectomy and a collostomy bag (for her waste incase you don't know what that is my spelling isn't the best). She survived that and was able to bounce back where then she started 6 weeks of 24/7 chemo and 6 weeks of radiation every day. During the time she was doing alright until towards the end she started getting in a lot of pain, always sick throwing up and going to the bathroom constantly and loseing a lot of fluids and weight. She was in the hospital twice for dehighdration. On April 13th (friday the 13th) I had to call 911 to rush my mom to the emergancy room cause she was in severe pain for about two and half days and had started throwing up black stuff. They had to do emergancy surgery becaus a part of her intestine had ruptured. My mom at this point was considered malnurished and they were worried she wouldn't even survive surgery or recovery. She did make it through surgery but still is recovering since with few set backs here and there. Now unfortunatelly when they did the emergancy surgery they put a new bag on her an illiostomy bag which is higher up on her intestines which means that everything she puts in her body just goes right into her bag and doesn't get obsorbed. This means allll of her counts are low such as her sodium, magnessium, potassium, and her blood she has had 4-5 transfussions so far. The concern is that the bag is going to keep putting out to much and they can't keep up with it and she will continue to lose weight she had started at about 220 before january and is not 125 and well it is all very scary. We also found out today one of her surgeons took a look at the cancer for the first time since before she started treatments and said it didn't look like it had shrunk at all and now they have to do another pet scan on her re-evaluate the cancer and what stage she may be. The worst case scenerio is that she has to have surgery to remove the cancer, recunstruct her rectum & vagina and fix her illiostomy bag all before her body is ready or strong enough to do so then we risk her not making it through the surgery or recovery. I am trying to do my best to stay positive for her and my step dad and also working on myself to get healthy but it is alllll so hard. I am asking for those who are spiritual and religious that you start a prayer chain for my mother you never know the power of prayer and what it can do so I ask anyone and everyone to keep her in your thoughts and prayers. Thanks, I know this is for weight loss support and motivation but I need it for not only my weight loss but for my fmaily as well.
