i think i understand a little better now, gina. if your therapist is good and you trust him, keep using him. it's your own choice whom you want to talk to about all your problems. but do consider finding a gender therapist as well, as soon as you can afford that, since it doesn't seem like your therapist really understands trans* issues.
i'm still wondering though, whether you dress up like a man in front of your father out of respect for him, or so you won't upset your mother even more. if your father didn't even yell insults at you, i don't really understand how you can show more or less respect by how you dress. or rather, i'd have thought that you'd be showing him more respect by giving him your true self to relate to instead of just faking it.
