Well - Cis-envy - a sadly common issue we all faced at one time, right? That women in the subway that has the perfecly female body shape or the most feminine face ... One should not think that its impossible to reach this because of being a trans woman, but simply one should try to think of it in a different way - that most other women do not have that perfect voice, face, body either - it has nothing to do with being trans and one should not start to feel "more trans" because of it or feel inferior or "less of a woman"... Its just that some women are more feminine and others are not ...
No reason to let it all slack, it still is worth trying to be your best and be as close to what you feel you should be like as possible
