Wow you are incredibly naive or you have a death wish. You didn't get help so you are going to poke the sleeping lion. I think you have more to worry about than the art group
aren't artists usually MORE free thinking and liberal?
Now here I have to really disagree. What if mom (hopefully) lives to be 110? Now Teresa is also 25 years older. Living with her secret everyday. Having it eat at her. Maybe even blaming Mom like she blames her wife for not being happy. Embarrassment goes away quickly. Living a lie kills you slowly. I think telling mom is not a bad idea. I don't think you tell the art group before you tell mom though
