It's all about control......just depends on what we choose to control it seems from my own personal experience......would rather be in control of a body in good shape & getting the right exercise & food, but it doesn't seem that easy when one's lifestyle isn't easily controlled & has no schedule or direction......

Keep working at it.....if you have some good periods, maybe they can be the ones to focus on & try to continue in that path & hold onto it for dear life.
