CS Phd Rejection

I just got rejected from UTD. I feel the worst. I applied to schools like Columbia, UT Austin, UCLA, purdue USC Rice and this one was my backup. I don't know what to do. I feel like I aimed way too high and got my hopes up way too much. I don't know what to feel or do. I didn't even tell my parents yet. I don't know how to get up. I don't know what to do
