I’ve posted in a mom group before, but I never got a response. Any support groups in NW Houston area for parents of children with mental illness?

My teenager was diagnosed with a mood disorder, depression, and anxiety last year after two failed attempts. He’s gotten a lot better, but I’m always on edge. I’m scared he’s going to snap at any minute again. Would love a place to be able to vent, or just listen to other parents struggling with the same thing.
