It's awesome when family we haven't seen in a while notice our progress, but I wouldn't stress about it this time. Just think about how much more
you'll have lost by the next time you visit!
Of course it's water! You can't gain 7lbs of fat in 2 days
I would say, just don't weigh yourself until you feel normal and you're off your meds. If you're eating well (despite the prednisone, which is tough!) you should give yourself a big hug! You're doing what it takes, taking the action
that will result in weight loss
I know it must be super frustrating not to see the numbers go down, but just think of yourself as a beautiful sculpture. There's a red velvet cloth that's covering you up right now, which is the water retention, but when you're "unveiled" --wow!!
