Was I right to leave my rp group after feeling like my player agency was violated?

Everyone. I was apart of a discord RP group but I recently left after this incident. To give some background. I was being repeatedly belittled OOC by other members and was being made to walk on egg shells around everyone. I was already Abit on edge the whole time I had been apart of this group which was for around six months. So this event starts and we find this group of nineteen children who had survived a horrific attack. They end up being affected by some unknown disease so we are all in quarantine with them.

This whole time my Character gravitates to this one little girl and makes sure to dote on her. Several of the children including her are confirmed to be orphans. My character is in her 30’s and I thought I would be given the chance to adopt her. Well the GM barely rped as her because they could not handle dealing with multiple players and scenes very well. They give us permission to just npc the children to an extent because they can’t keep up. So I am just writting scene after scene the whole time of cuteness. I am ignored by most the players and the GM even when I try to interact with others but I just play it off and try not to let it bother me.

So after the event ends the GM announces that the particular little girl I was taking care of was adopted by another player who hadn’t even met her. Needless to say I was very livid. I ended up leaving because I felt like no one was taking me into consideration or even allowing me to really interact with the events. Two players reached out to me to try and get me to come back even though in there own words the mods were "Cold hearted." I didn’t talk to the GMs about it because I was so mad and hurt to be stepped on like that, nor did they ever try to reach out to me. Am I just being childish here or am I in the right?
