It is very hard to not feel well and unmotivated to do what you want to. Hopefully your medical team will figure out what is going on very soon and find the right therapy to get you on your way to health.
All you can do is try to take control where you can and hope the small things you do will not only help you feel a little better but also help you take small steps forward toward your goals. SparkPeople's Mind Over Body plan is designed to give you the tools you need to identify, work through, and overcome the most common emotional and mental (attitude) problems that people face when they set out to change their lifestyles. www.sparkpeople.com/resource/mind_over_bod
