Your health and vitality ought to be strong and robust now.  This is a great time to correct bad habits if you need to do so in order to protect your health.  Starting with small goals, like a daily ten-minute walk, could very well lead you to where you want to be, which is even healthier and stronger than you’re feeling right now.  Yes, it can get better!  This is likely a very spiritual time for you, even if you don’t have anything close to a religious belief.  To be truly strong, you must pay attention to and develop each leg of the triad we are made from:  body, mind and spirit.  Be sure you are spending time on all three.  That’s hardest to do when things are difficult.  If you are at a low point, know that things are very likely to be looking up soon.
