rushing with a low gpa

im a senior in high school and all through high school i've taken very difficult honors and AP courses and struggled through depression this past year and i ended up with a 2.99 after struggling through all of that. I was wondering 1) can i still get a bid from a house 2) if my entire gpa from high school will count including all of senior year 3) how do houses get to know our gpa? Thank you!!
