Opinions?

Soooo I'm a senior and I turn 18 in abt a month. My whole family wants me going to college where all of them have. I want to go to Washington, preferably seattle, to be with my SO and bc I want something new and challenging from the midwest life ik, plus I think I need to distance myself from them to figure out who I am bc I've always done whatever my family wants. I finally got the balls to tell my mom... over text. And she brushed it off and didn't even respond. I need help looking for the right college and $ for applications so I can't just say screw it I'll do me... but idk what to do bc they (parents) have literally told me im the hardest to raise. I don't want to be more of a disapointment than I already have. I am completely lost and feel like I got 0 support from my fam bc I want to be different and figure myself out. Please tell me what u think.
