I'm stalled

I've been stuck around 146 for the past month or so. It's really frustrating. I know I have fallen off the wagon in some respects so I guess I'll try a little more discipline before I do anything drastic. My cat has been very ill. She is so skinny. I took her to the vet on Monday. They ran lots of tests but didn't find much wrong with her other than potassium deficiency, arthritis, and fleas. She is taking a calcium supplement, pepcid and is eating special food. She's 15 years old but I'm not ready to lose her. On the bright side, I went shopping on Satruday and bought six new pairs of pants. They were all size 12! 218/208/146/115
