I don’t feel like my family is proud that I’m graduating

So I’m the third child out of 4 kids I’m the only girl and my 2 older brothers never got to graduate with there class the oldest got his ged and the second oldest got his diploma a year after and never walked. I was always considered the “bad kid” of the family cuz I fought and talked back so sadly they expected me to be like my brothers. I got kicked out of my first high school and went to home school my grades were never good but I did pretty good at homeschooling I’m a senior of course and I am graduating on the 30th I’m really proud of myself because I was told I’d never be able to do it from a lot of people even my dad and I proved them all wrong but it’s like they don’t care my parents are divorced and my dad doesn’t get a lot with my mom or my step dad and my oldest brother doesn’t really talk to us anymore and my other brother is 14 hrs away I don’t know I just don’t feel like it a big deal I’m the first kid that gets to walk on stage and get their diploma handed to them but it’s like they’re not proud my boyfriend keeps trying to ask me what I wanna do and I don’t want to do anything cuz I feel like it’s not a big deal to people i don’t know.... I haven’t gotten anything for my graduation either I don’t have a dress or shoes or the way I want to do my hair I just kinda don’t feel like even going to my own graduation it sucks..
