Love and acceptance. Two of the greatest things on the planet. Or anywhere else, I imagine.

  Hi K.C., i would pretty much just echo most of the other suggestions and good ideas already given to you. 

   When those difficult feelings arise, just remember how loved you are.   Totally and completely loved by Source, your Greater Self, and loved by some of your family and friends.    Love yourself, look into a mirror, say your name and say something like "you are one wonderful and beautiful person!"   

   You are, you know. 

  And if you start to meditate at all, ask for pure universal love to fill, lift you up, and surround you before meditating and while meditating.   Believe it will, and it will.  Belief and beliefs are very powerful things.
