I need to have an ostomy, please help!!!

My name is Maria, I'm almost 28 years old. I have a big, big problem. I have suffered from Ulcerative colitis for the past 4 years, and the medications didn't work as hoped. So I have basically been very ill for the past 4 years, isolated in my home. This led to a severe depression, which resulted in overeating. I had to take cortisone several times, which added to the weight gain. I had basically given up on life, when I realised that surgery could save me. To get an ostomy bag. My doctors had mentioned it to me, but I always thought that would be worse than anything else. It felt so, "final". But I actually started to feel hopeful, so I took the discussion more seriously with my doctor. I was told my weight might be an issue, since it would lead to problems with leaking bags, that sort of thing. The surgery itself could be more difficult as well. So, I lost the weight. With much effort I might add.

Now I'm in a new situation, where the skin on my stomach is very saggy, and my doctors tell me it will be more difficult for me to carry the bag, since it will be harder to make everything "stick" to my skin. It would be ideal to have a tummy tuck prior to the ostomy surgery, but I can't afford it. I am also unable to work due to my condition (I can't leave the house basically), and nothing else I tried from home has worked (I tried blogging, YouTube, and all sorts of ways to earn money, but it's never enough).

So basically, when I finally accepted the idea of having my colon removed, I first had to lose all the weight I gained because of the horrors I lived with. Then, after I managed that, I am confronted with saggy skin which could make life with an ostomy very difficult. And I can't have the tummy tuck without money, which I can't get since I can't leave the house. I'm gonna be 28 years old soon - this is not how my life was supposed to be :(

I can't post pictures of myself, since I don't want pictures of this to be spread around the Internet without my control. In this day and age, there is no guarantee that pictures of people in distress with "less than perfect" bodies aren't used for mockery. I can't risk that. I am instead posting a picture of how my stomach looks like, since it's pretty much the same as on this picture.

Please help me! Without your help, I will be stuck in this hell with no way out. If you help me, I can get the tummy tuck, then I will be able to get the ostomy bag, and then I will be able to get my life back...
