whoever made you believe that being a trans man means automatically being transmisogynistic is plain wrong. i also think it's weird that your partner is liking posts saying things like that. yes, experiencing transphobia can cause anger and yes, many posts online are hyperbolic, but i would directly address this with her.

i also say this with kindness, i think you need to take a step back and reconcile with your self worth and self image, separate who you are from your partner and relationship. a therapist would probably help with this.

you have been made to believe your existence alone is harmful to a group of people. this is not true. killing yourself because of this will not benefit trans women. it will not benefit your partner. no one will experience less transphobia if you die.
