Sign language has helped me get out of a dark place in the past. Because I was now able to express myself and had a voice, in a way. But it has its uses and I can't say that it replaced my actual voice. Sometimes I sign while I speak. It's not a difficult language to learn. Language learning is always beneficial to mental health. I have friends that also speak ASL. So it depends on your situation. And I wouldn't worry about the 'being offensive' thing. Only the french act snooty about their language hehe. I keed.
