My mom and my best friend (cis woman). My mom immediately accepted me and told me when I came out to her that she would love and support me no matter what I’m about to tell her. She accompanied me to every appointment whenever she could so far.
My best friend immediately made me feel like one of the girls and treated me like any other woman. She was the second person I came out to. I can talk to her about anything and she is very empathetic and gives me great support emotionally.
Edit: but I also have to add that I didn’t make any negative experiences since my coming out so far.
