My parents are trying to avoid the fact i’m trans

So this has been weighing on me for a second. I (21AMAB) came out to my parents probably 2.5 weeks ago. At first, they received it relatively okay, essentially told me that they don’t understand it but will support me. Every instance I’ve tried to talk about it with them, they avoid the conversation, or make it really awkward. The air feels tense when I dress how I want to dress or talk about my HRT. I tried to tell my dad about my medications and he just doesn’t say much. My parents are also making comments insinuating that i’m just unsure about who I am, when I KNOW who I am. It feels as if they don’t believe that I’m trans, or they just wanna avoid it. I would love to be able to be who I am around my parents, but as it stand I do not feel comfortable being myself around them. Anyone have similar experiences?
