Shocking myself

I've been a MFP member since 2010. Initially I lost about 40 pounds but then I gained it all back and then some. In January of 2015, I was weighing in at 260 pounds. I have multiple sclerosis and my body had been ravaged by it. My muscles were atrophied and I was wearing a size 24. I am now weighing in at 175 and I have been here since summer 2015 so I managed to drop 85 pounds in six months by watching my calories and working out religiously. My before photo wasn't even at my highest weight. I was around 230. The after photo was taken at 180. I am 5'7"
