Help for a Friend with Body Image Issues

Hi guys! I have been using MFP for a long time, but I tend to keep it private. Just my style. So I am new to this forum, but I am hoping to get some advice.

My best friend has a pretty dismal body image. She constantly complains, and I mean multiple times a day, every day. All the time. I am just at a loss. I've tried building her up, I've tried ignoring it, I've tried focusing on other non-weight related aspects of her life (career, etc.), I have suggested counseling...I have seriously tried everything I can think of.

At the same time, I get it. I am not the happiest with my body either, although I am working on my own body image. I lost about 30 pounds about 9 months ago, and have kept it all of. I am in great shape, but let's face it, we are all our worst critic. So I totally understand feeling negative about our own bodies. But it's just CONSTANT.

It is bringing me down. I just don't know what to do. I want to support her but I don't want to be dragged into the negativity, etc. It's to the point where it's affecting her life and our friendship. Advice welcome.
