Hm. That L sounds like she doesn't really want to deal with your situation. You may want to talk to someone else. There are plenty of Ls out there, and you may have to meet with several to find a good one.
Did you get any information about your rights when it comes to your children? Maybe you need to find a L who understands the issue of father's rights?
