Is committing worth it?

This same type of post has been made before, but I would really like some advice.

UPitt is my dream school and I toured it over the summer, fully planning to commit if I got accepted. Now having been accepted, I’m realizing theres just no way I can afford it as an out of state student. My family is poor and the most support I will receive is 2k per year from my grandparents (which i am very thankful for!!). I scored a -1500 index on FAFSA, and have not received aid information yet from Pitt (I heard they do not send out information till mid-end February). I also have 6k saved from working part time.

Tuition is probably 45k? yearly for Pitt and based on this information i have no idea if i can ever afford Pitt and its kindve heartbreaking to me, but I also care more about not being completely in debt. Any advice would be great!!

I plan to major in Computer Science, and my state university has a good program for Computer Science I believe!
