My best friend is out of town right now visiting friends from college. She visits them maybe once every couple months or so. I don't know why but everytime she does I get this sad/lonely feeling. I try so hard to fight it but it always comes back. I always seem to have to fight these feelings that I'm not good enough, that I'm easily replaced, and that she will leave me. I feel crazy for feeling this way because she is a loving, loyal friend. It all comes from my own insecurity I guess. I have this voice in the back of my head that says "she's having so much fun without you. her other friends are so much better than you". I hate feeling this way. I am ashamed of these feelings because deep down I know what I'm thinking isn't true and I want her to be happy and she deserves to spend time with her other friends too. Ugh I hate the way I think sometimes.
