I agree with Rob. Your mother doesn't sound like a safe confidant. Definitely don't tell her if you are financially dependent on her. There's an organization called Parents, Families, & Friends of Lesbians and Gays that could probably be helpful. (www.pflag.org/) Contact someone there for tips on how to educate your mother over time so that you can eventually tell her who you are and have an open and honest relationship with her. Good luck. It's a tough spot to be in.
