I'm finally feeling like I have a grip

So I've gained 5lbs since September and the jeans that I want to wear are not the ones that fit. To fix this, I started going to the gym again and BOY, I FEEL GOOD! I need to get addicted to exercise, addicted to honouring my body by putting good food in it and working to make my heart healthy. I hurt, but it's a good hurt - I feel like FINALLY I am getting a grip.
