DEFINITELY take some time for yourself. The gym is a great way to relieve stress, but if I didn't have my 15 minutes of TM (meditation) and tea in the a.m., I'd never make it through work. Or my Sunday bubble bath. OHHHH, I can't wait for Sunday you guys.
It feels so good to take care of you. When you do, you recharge and you are better as a mother, W, whatever.
You're doing great, keep it up, the weight will come off.
Try self hypnosis as well. It works for me. I repeat to myself constantly "I WILL lose weight, I LOVE to work out, the weight just drops off of me..." After a while, your subconscious mind believes it and does what you keep telling it to do. I know you have a medical condition, but I believe in the power of the brain. Believe it and it will be.
