Do like this: Mom! I need a binder for sChoOl purposes

If so, you could say mom is it possible if i could get a binder to help me feel more comfortable in my body [i don't really know if it a good idea or not but u can try]

First thing is do your mom support you?

Mother I require a chest compressions device to almost feel complete gender euphoria

Just walk up to her and say “I request a binder”
