Gay mental health books

I'm big on self-development, because it's really helped me get confident as a gay man. Does anyone recommend any self development type books written by/for an LGBT audience because there's not many? My own favorites were The Velvet Rage by gay psychologist Alan Downes (as a beginner on my journey, I wouldn't read it now), Out of the Shadows by Walt Odets (slightly more advanced but slightly depressing again, I wouldn't read it now) and Feel Better No Matter What by gay life coach Michael James (who's like a gay Tom Hardy). Any books you suggest that helped you on your self development journey?
