I don’t think my parents are taking me seriously

A while ago I came out to my parents as trans. They lectured me for ages about how “I’ve never shown any signs” and how “teenage brains are weird” and all that shit, basically what it came down to was “no you’re not”. Anyway I eventually convinced them to start using my preferred name, although they don’t use my preferred pronouns. They haven’t had any sort of conversation about it or tried to support me. One time I convinced my mum to take me to the shops to maybe buy some more feminine clothes, but when we got there I freaked because I was worried someone from my school would recognise me and we left. In the car on the way back I said to her “I’m sorry I don’t think I really thought this through”, and she said “no, I don’t think you thought any of this through”. That was like half a year ago. I don’t think we’ve talked about me being trans since. I sometimes wear skirts around the house and they don’t say anything, but I rarely do that because my sister judges me for it. I started going to a social group with other trans teens recently as well, and my parents both seem quite opposed to it, even though they haven’t outwardly said so, and when discussing potentially getting hormones and medical care I can tell they’re not happy. I feel like as I get closer to potential medical transition the more tense things get and I’m worried it might get to a point they’re going to directly oppose me if I try to get hormones. I’ll be 16 by then, and where I live that means there are ways I can get it legally without parent permission, but I want to have a relationship with my parents and it’s really hard when they seem to think they know better when it comes to who I am.
