Lynette,
It's the hormones plus all the other stuff going on at your job.
Might help to journal how your feeling, try very hard to get your protein, take a leisurely walk .
It's the lack of hormones mainly. Remember how somepeople feel just when they're having pms or going into menopause.
Get those hormones as soon as possible.
Remember, this will pass. Hangin there sweetheart.
ps I can't imagine anybody not getting along with you! Must be something wrong with those peeps.
