STARTED TENNIS TO WORK OUT, LOVE IT BUT HAVE NO ONE TO PLAY WITH (HELP)

I am looking for a group to join to have fun learning to play. I am a beginner but I am falling in love with this game, just need to surround myself with people that feel the same. Someone let me know where to begin. My email is catherinecooper@rocketmail.com and my name is Cathy. Thanks.....
