Tired of feeling tired

I am just starting to get back on the train. I have gained over 50 pounds in the last 4 years, and the last 25 pounds were just in the last year. I need to get back on track as I am turning 40 in a couple of weeks and I have alot of health issues that I am dealing with. I lack motivation, I have anemia so I am super tired all of the time, along with Asthma. I want to feel better and be healthy, it is not all about losing weight, but its about being healthy. I need someone who will hold me accountable and ask me if I have been healthy everyday, to keep it in my brain.
