HATE my HUGE belly!!!?

I am about 5months pregnant not throgh choice it was to late to abort, and my belly is HUGE. Even the doctor said it is much bigger than it should be at this stage, more like 7 or 8 months. I am carrying triplet girls so my belly is expected to be bigger than normal, but not quite this big!! As I don't want to be pregnant and have such a huge belly I'm getting really depressed, I feel like my belly is a burden and I hate it!! I wasn't planning this at all and need to save every penny for my babies, so I am wearing non maternity clothes, an my belly just seems to dominate everything. I feel fat and heavy and I just want my horrid balloon belly to go away, so I can move about without a huge lump in the way. I know I need to get used to my belly but I really dom't know how and am dreading it swelling any more. Please help.
