(TX) Can my parents take back gifts they’ve given to me?

I’m eighteen and lately my relationship with my parents has become exceptionally poor. I’ve gained things over the years like a computer, handed-down phone, and several other electronic devices all as gifts from my parents. These items play a big role in my life now as I am transitioning from a life at home to one outside of their influence. I was wondering about the legality of them taking away these items in light of my current relationship. I don’t necessarily have the ability to prove definitively that these items are gifts and as a result I’m very concerned about their emotionally abusive threats to me about taking away these items I need desperately. I deeply appreciate any advice in my current situation and am more than happy to clear up any questions about my given situation.
