There will be times you are angry, sad, upset... whatever. That's the way it goes. There isn't any "right" way to feel. God knows, I was angry at my W for putting me through this plenty of times. It's all normal, and healthy.
There will be a lot of times you are taking two steps forward and one step backward. Don't beat yourself up over it. I think it was 25yrsmlc who reminded me that "it's not a linear process."
Good for you for making definite goals.
