I am a 43 year old mom of a teenage son and two children in their twenties.  I have a grandchild.  Over the course of the summer I have discovered that I have a enlarged thyroid and I am also pre-menopausal.  I have gained 30lbs and I am having difficulty losing it.  I am a huge procrastinator and I am having a difficult time getting into an exercise routing.  I know I just have to get started.  Any help or suggestions will be greatly appreciated.
