"I can't do this." 

"The meal plan is too much work."

"I can't stand my body." 

"I'll never be able to manage my diabetes so why bother?"

"I don't have time."

"I'll start recovery after I lose some weight." 

These thoughts are limiting.  They limit your recovery, and ultimately your life.  To live an expansive, vibrant life you need to start thinking and behaving in ways that are more empowering.  "I can't do this," becomes, "I CAN do this, even though it's hard and uncomfortable."  Give yourself credit, I guarantee you are stronger than you think you are.  Reframing your negative thoughts into empowering thoughts gives you the space and opportunity for change.  The limiting thoughts are like throwing in the towel and giving up.  That isn't going to get you anywhere but further away from your center.  Yes, it will be difficult.  Yes, it will be uncomfortable.  Yes, you will need help and encouragement along the way.  Accept these things and start putting one foot in front of the other.  You CAN do this.
