is there any sad/depressing post rock album or songs?

tons of em

that's basically a hallmark of the genre

literally the entire genre

You've clearly not listened to any post-rock album if you felt the need to ask this. There are literally thousands of them that are atmospherically melancholic.

Is there any happy/upbeat post rock?

yes there are. plenty of those as well. It's become a trope that post-rock is supposed to be moody or melancholic/downbeat, but that's just false.
