My older brother is not supportive of my interests

Hi coven. Love you all 🖤 My brother is unsupportive of my interests and has been for a long time. I show him my drawing? He says nothing. He sees the 4’ by 4’ painting that I’ve been tinkering with for literally years? He says nothing. I show him my wardrobe (fashion is important to me and part of my identity as a person). He insults two of my bags and calls chunky black necklace a “boomer necklace” in a derogatory way. I tell him I’ve been upcycling jewelry? He says that’s not original and lots of people do that. Why can’t my own brother be supportive of me? I’ve pointed this out to him that he’s unsupportive. But he still never checks in on me or cares what I do. I told him I’m struggling a lot with suicidal thoughts, and he says “since you’ve been struggling with your mental health for so long, it’s starting to get hard to care if you die or not.” I got him a multi-part gift for Christmas. He got me nothing for Christmas and nothing for my birthday.
