Coming Out to The Rest of My Family

I just came out as trans to the transphobic side of my family! I am only out to my dad, sisters and uncle. I made it a post on Facebook since i know they use that. I'm so nervous about what they'll say, if they even say anything at all. My brother that i wasn't sure about(like if he is transphobic of not) actually messaged me saying "RIP 'deadname' welcome Xylo" and that made me so happy. I feel like he will be the only one of that part of the family that will accept me. I know for a fact that my grandparents won't. I've come to terms with that and the fact that i'll probably never talk to them again, not like i really did anyways :/ 

I am still a little sad about it though because they still are my family and i do love them and i wish they would love me for who i am. But they have also shown me that they wouldn't and they don't seem to care about my sisters, my dad and I. My siblings are a bit separated, my two brothers got adopted by my aunt and uncle when they were babies and i wasn't even born yet, so my sisters and I weren't raised with them, and only see them on holidays.  We (my sisters, dad, and i) weren't even invited to thanksgiving this year, at least that's what we think. my dad called my grandma to tell her happy thanksgiving and she mentioned she was over at my great grandmas house( where holidays usually are). there are also other reasons i believe that they had a separate thanksgiving. but my great grandparents decided that that they're not doing them anymore,(which is understandable because they're getting older)  so they did a thanksgiving and christmas dinner thing last week. My sister did a separate thanksgiving today with just her husband and his parents, me, my other sister, my dad, and my uncle because the usual one wasn't happening. I actually had such a good time and i wasn't dreading it like i usually do. i was called by the right name and pronouns (im out and accepted by all of them) and it was so nice.

I have been thinking about coming out to the rest of them for a long time but i wanted to wait until after my sisters wedding(a few months ago now) and after the holidays. I've been so nervous to do it because i knew that would mean i would never talk to them again. but after my grandparents didn't stay at my sisters wedding for more than an hour(they left right after the actual marring part, which was the first thing that happened, for a fucking nascar thing) and today where they're having a separate thanksgiving, i really realised that they see us as a different family. my dad always told me that they treat us(my sisters, dad, and i) differently than the rest of the family but i guess i just really saw it now. it's so disappointing. But they never really talk to me so i guess nothing is really changing. but i'm so glad to see other parts of my family that i don't really talk to or see showing support on the post i made. sorry for the long post, if anyone is even reading this ._.
