I had a breast reduction (G to C) done just when I was diagnosed with Lupus. I had decided on this years before and had decided I would do it after having my children. The surgery and recovery did not present a problem. My only caution would be the reason behind the augumentation. It is not a quick fix to relationship problems nor to your depression. I suggest you deal with the underlying issues before embarking on the surgery. Healthy eating, exercising and managing my Lupus is where I started.
