you hit it right on the head. It takes time. Time and continued effort. Change is slow. Think about how long you have lived in the pattern you did. All the years that you reinforced behaviors that might not have been healthy. These things wont go away over night. So it sounds like you are headed in the right direction. You have taken obvious steps to BEGIN to unravel the negatives. You also seem to be in an open mindset to be able to recognize not only this need for change but that it is a process.

Maybe try keeping a diary or journal that logs your thoughts and successes. This will give you something tangible to look at when you are "having a bad day". Don't give up, remember that in any race uphill is the hardest but once you reach the crest its all downhill!
