Trying and wanting to be healthy

I just woke up less than an hour ago and now I am too tired to muse on anything except for the error of my ways.  It is about trying to be healthy.  I am worried.  I admit that my eating habits are poor yet my exercise regimen is better.  I am concerned that my health will get worse despite the fact that I am exercising and making a long term goal of losing weight and living a healthy lifestyle.  Maybe if I were to figure out the healthy lifestyle part, then maybe I would know what I am doing.  The truth is, I don't.  I need help and I need support.  But most of all, I need wisdom and knowledge.
