The best thing you can do to be supportive is to honor her request to switch pronouns over at the time she requested . You might also inquire as to how she ' d like to be referred to . you obviously know her as ' mom , ' but finding another title might be affirming for her . Be sure to tell her you love her no matter what . Your parents ' relationship might suffer , might even end , but I ' d give them some time to work things out between themselves . If your mom does wind up looking for new partners , there are some cis gay man who are cool dating nonop trans guys . That ' s something your mom can navigate and figure out on her own . And what I ' ll say to you , a sixteen year old whose parent is going through something intense , is Practice selfcare . Don ' t put responsibility for your parents ' happiness on your own shoulders . Give yourself time to adjust if you need it . You can and should try to be there to support your mom , but make sure to take care of yourself first . It ' s okay to feel whatever emotions you feel , and to take time to process them . Treating yourself with kindness is the first step to treating others with kindness .
