My Parents Sent Me a Birthday Present

For full context, I have come out as trans 3 times to my family. First in middle school, when they dug through my phone without my consent and then shamed me for it. My dad barked at me with gritted teeth "Stop fucking up your life." Second time was in high school when I tried to get HRT and was told we couldn't afford it and I was being hysterical, mom and dad went on a cruise that year so money must not have been that tight. Last time was in August, I thought third time would be the charm but all I got more insistence I was being silly and that was the final straw. I haven't seen my parents since a little before that last attempt and it has been incredibly hard. There were some other awful moment in my childhood (my dad calling me "a gay," my parents threatening to kick me out of the house at 16 over poor grades, both of them physically hurting me at times) but this was the breaking point, the only thing I can't bring myself to forgive.

I turned 23 on the 13th and got a gift card from them via text. I thought it was a scam text, the link itself looked shady and I got a separate text telling me to respond "X" to the first text to opt out of notifications so I think I had sound reason to believe so. I just had a birthday meal with my sister and she told me the gift card was real and we had a giggle over how I just burnt $50 on gut instinct. This leave me in a tough spot however; I told my mom that, unless there is an emergency, I don't want to hear from her or dad until they can accept me as their daughter. I also feel I owe a thank you to anyone who buys me a gift. Do I send a thank you and hope it gets them to see me as their child again? Just thinking about this makes me want to cry, this isn't a dilemma anyone should have.
