Struggling with family's reaction to my hijab choice

Assalamu alaikum. I need to get something off my chest. I'm South Asian, and in my experience, not many Muslim women in our culture wear hijab. Growing up, no one told me it's a command from Allah-adults just said you wear it when you're super religious. So as a kid, I thought you had to be a hafizah or something. My home wasn't religious at all; I wasn't taught to pray. But alhamdulillah, as a teen I found Islam online and started praying regularly. Then I wanted to wear hijab, but my mom (who doesn't wear it) didn't let me. After lots of convincing, I finally got one-but my dad told me to take it off on the second day, though I didn't listen. Now, I'm the only one in my whole extended family who observes hijab in front of male cousins, which is tough since many relatives live in a joint family system in India. When I visit from abroad, I keep my scarf on all the time, and I get eye rolls and comments like 'don't overdo it.' They talk behind my back-I've caught them. At weddings, even if they're 'segregated,' there are always male photographers, so I wear hijab, and it upsets my family. What really hurts is my mom putting me down. She says I don't understand the 'meaning' of hijab by being so careful about covering my neck and hair. The irony? She praises distant relatives who wear hijab at weddings, but when I do the same, she says, 'It suits them, not you.' She's stopped calling me out in public after I shared how much it hurts, but she still mocks me at home. How can I get her to stop? JazakAllah khair for any advice.
