I'm just salty.

So I have trust issues with everyone, especially my family but my older sister just tried to use the dumbest logic on why I should still trust her. So basically I subtle said I was bisexual (I'm straight/aromantic now people change) in a conversation with family since she called me gay, not to mock me but to just say I'm gay because shes stupid and thinks it's okay to just classify your siblings gender when they're ten (she called me gay a while ago but a lot) and not let them decide on their own. So when we saw each other after the conversation she asked me a lot of questions and I just was in a terrible place and vented to her about wanting to kill myself, hating our family, and having a lack of emotions but faking. I thought I could trust her, THOUGHT. Nope as soon as she got mad at me she tried to threaten me with it saying she'd tell everyone I'm an asshole and I don't feel emotions. I was worried cause I didn't want that and they already hated me enough. She has the habit I thought she got over of blacking mailing everyone in her life, especially me, once she found a diary I had written in when I was like seven that I had wrote because I hated my parents and they had just beat me for no reason other than pure assholary, eventually I burned it but every chance she got she'd put me under her thumb and blackmail like there was no tomorrow. So of course after she threatened me I lost my trust in her. Just a few minutes ago she asked me why I was so jumpy whenever she pulled out her phone, and when I said I thought she was recording me, we got in an argument about why I apparently didn't have the right to not trust her, and I brought up how immediately after I told her personal stuff she threatened me, and she said in all her glory, "I didn't threaten you till you pissed me off." So I'm cringing internally about how she thinks it's a perfectly fine thing she threatens me with personal things after I "piss her off" and I should still trust her, what do you think?
