I feel really gulity today

A very close and dear friend told me today that due to a death in her family she was Inheriting a large amount of money. I love this person very much and would say that at this point in my life she is my best friend. even though I am very happy for her I am very jealous. I feel really guilty for feeling that way and ask god to forgive me for being so selfish. What is wrong with me. I dream and say a prayer every night to win the lottery (which I always forget to play). I just want to win enough to get me out of this financial problems I'm having. I have even gone as far as saying to god in my prayers if I win more I will gladly help other that need help like I do. I am not a selfish person and really enjoy doing nice things for other. I get a true joy out of doing for others. I just want to get a break of my own. I know we are not suppose to question the journey god has sent us here complete. I just wonder what I'm here to learn. Any subjection on this let me know. Thanks for reading.
