How do I come out again

 Hi so basically I like don’t know how to tell my family I’m agender.. I changed my name too I don’t exactly mindd ppl calling me by my old name but I don’t like it either.. I came out a few times like a few years ago (bi, lesbian, pan) but they’ve always seen me as a girlll and my parents might support me but the rest of my family probably wouldn’t sooo!.. I don’t know what to do I also wanna tell my friends my preferred name but what if they think it’s STUPID !! Only 1 of my friends know.. and that’s my best friend.. UGH!! Anyway I’m gonna go play blocktales :P
