Is my mom toxic or am I just a typical rebellious child?

It seems like my mom is CONSTANTLY bringing me down.

I wanted to be apart of the military for a long time since I was 12 (I'm 18 now) and when I first told her, she said she didn't know if she could talk to me if I joined. So I pushed it out of my head for years. And I told her "no I'm not going to. I don't think I should." And today, I talked to some co-workers who were ex military. And it re-inspired me and she asked what I talked to them about and so I honestly told her and she got all quiet and passive aggressive and I asked what was wrong and she's like "oh nothing..." And give me this dumb little look and I said okay. And then later she's like "I just thought you were over that. You always change who you are around people. Once they mention something you take interest." She basically continued to called me fake and said "you change who you are based around the people you're with." Which is total bullshit. It's complete SHIT. And it pisses me off. Like it hurts. Why would she say something like that...? I know when I was younger I didn't know who I was and I was trying to figure it out. And I tried a lot of different sports to see what I liked. But she just goes and says that?

And at Christmastime she and my dad told me that I do things for attention and for a reaction. They called me a liar and someone who basically overreacts and does things so people will pay attention to me. Which is also complete bullshit. I've been wondering if I should even type this out. But it hurts so much when your own family says stuff about you like that and what's worse is that my dad just immediately takes her side so I have nobody to go to. It's so dumb and it makes me so angry and sick to my stomach. I don't get mad easily but I literally almost smashed my plate today. I blew up which wasn't right but how could she say that stuff!? And she's gonna spread it too and tell my dad and he's gonna take her side. She said "you always do this and change who you are depending on the people you're around.." and I said "REALLY? Tell me times. I've done that. TELL ME" and guess what... She stutters and couldn't say a damn thing. And I looked at her and laughed and said "yeah? You can't even say anything.. you can't even tell me a single thing. You're a joke" and she proceeded to call me mean and tell me maybe we shouldn't talk. Believe me, I would leave but I don't have a license or a car and I depend on her for so much it's driving me insane I'm so fucking done with her shit. Right when we get along. She says something awful to me about who I am and it hurts so badly..

I just need to know if I need to woman up and if she's right or not.
