Medical issues really complicate our dietary intents. I'm so sorry you're having to deal with this.
I occasionally pick up a bunch of water weight for no apparent reason. When that happens, I get the routine: restrict fluids, cut salt, double the furosemide... and I can tell you, it's h*ll. Thankfully, it doesn't happen often, but any at all is too much. The frustrating thing is there's no way to figure out WHY it's occurred. That would be helpful.
So far as management, the first thing is naturally to follow your doctor's therapy. Someone mentioned yoga, and I will add to that Tai Chi. That's a very soothing and gentle "physical meditation", and might help with both the physical and the mental/emotional aspects of your troubles. I picked up a series of Tai Chi DVDs on eBay, which are very nice. Even if not for the medical side, it's a nice adjunct to improved health - both mental and physical.
I second the idea of having a specialist. The typical GP is likely to just prescribe a diuretic and tell you to watch your salt. While that's good advice, it doesn't address the reasons for why it's happening. In my case, I think it's associated with my autoimmune condition. Seems like everything is, one way or another! But in your case, the reason needs to be investigated more thoroughly, and a specialist is the best bet to do that.
Hope you can find some answers and ways to manage it.
