I am a hard worker but have never been able to get ahead in life. I have a good friend who is successful at everything she touches. She is a really good person, she never flaunts her success, and she is very generous to me. After I am with her a while I am undone and unsatisfied with my life. I am happy for her, sad for me, but I find myself talking against her. Is this jealousy getting the best of me?
