I'm stuck at the airport! I wish I had packed my passport in my purse instead of the TV remote.

If only I hadn't stayed up until 3 AM watching alien conspiracy documentaries!

We use "wish" with the past perfect (had packed) to show we are sorry that something happened or didn't happen in the past. Using the simple past (packed) would incorrectly refer to a present or future wish.

If only I hadn't stayed up until 3 AM watching alien conspiracy documentaries!

"If only" is a slightly stronger, more emphatic way to say "I wish." Because the staying up happened in the past, we use the past perfect (hadn't stayed).
