OP that all sounds tough for you, actually all of you.
How did your brothers cope?
Also you said earlier on about not liking your body because you felt fat. You also said "As a trans woman, wanting to pass as a woman, she would lean towards stereotypical feminine clothes, makeup, slim etc"
I get the feminine clothes, makeup etc but women are not necessarily slim. In fact many (like me) are the opposite.
I did wonder if any potential issues with food for me came from the fact my mum was very slim and fed us small portions and at 22 I 'branched out'.
I've had counselling and for me it is OCD that had led to food issues.
Neither of my parents is trans (but a young family member is). So I guess a lot if us get a 'cultural' as well as biological legacy from our parents.
Did you? So my second question is has your dad's view" about what makes a woman, negatively impacted you?
I should day I am trying to address being fat due to health issues and not because of how I look.
