In advance, sorry for the formatting I'm on mobile (also throwaway because friends know my account) 

So first off here's some background information. I'm a high school student and around the last couple of weeks of December last year I came out to my parents as bisexual. They did not take it well to say the least and my mom spent 3 hours questioning me and asking how and why I was bi and insisting that it was a phase. The following week my dad wouldn't even talk to me and was extremely serious. My mom told me that I would not be receiving any Christmas present from them that year. During this time I felt miserable and seriously considered taking my life. They ended up giving in and gave me a Christmas present and things started getting better over time since we would all ignore the issue and not bring it up. 

Fast forward to today, I'm in the car with my mom as she's driving me to school. We were listening to music when out of nowhere she asks me I still liked the girl that I had told her I liked when I came out to her (I'm a girl). I shook my head, not wanting to bring up this conversation. She kept insisting and asked "So yes? Why are you ignoring me? " I told her that I no longer did and she wouldn't take it for an answer. She once again asked and I raised my voice and told her again that I didn't and asked her to stop asking. She said she wasn't sure because it seemed like I was avoiding the question. I stayed quiet. She then proceeded to say "So have you changed your mind about it then? " in reference to me being bi. This was my breaking point and I raised my voice even more and angrily told her that I don't and won't ever want to discuss my personal life with her so she should stop asking. She said to me in the same tone that she was my mother and that there was no one better to talk about it with. I stayed quiet for the rest of the ride. When she dropped me off at school I got out and she said bye I love you as always but I got out of the car and ignored her and walked to class. 

A little later I texted to ask her something and there was an obvious distance. We usually say "bye love you" at the end of the conversation but we didn't this time. 

Now I keep thinking about how I reacted I can't help but think about me upsetting her and making her cry (she's told me in the past about how I make her cry when I raise my voice at her and disrespect her). Looking back I acted very childish and I feel like a total asshole. From my mom's perspective she was probably just trying to be involved in her child's life but I can't forgive her for "changed your mind" comment. I'm very conflicted right now and I think I might have been in the wrong here. 

So Reddit, AITA?
