I've had friends like this too. When the friendships ended and after I got over the hurt I realized I was relieved. These people are blood suckers. My advice is to pick a charity that you can identify and feel strongly about. Get involved and I think you will find a need there, be it an animal shelter, woman's abuse shelter, seniors home etc. You will feel fulfilled when you donate something you've created because it means so much to those who have so little.
