Realized I Missed the Start of the Last Ten Nights and Feeling Worried

As-salamu alaykum everyone. So I only found out today that the last ten nights of Ramadan had already begun. Turns out I completely missed the first night yesterday. I was actually awake pretty late, but it just didn't occur to me that they'd started. I honestly thought they were starting one night later. It's really got me feeling anxious because, even though there's only a small chance that first night was Laylatul Qadr, the thought that I might have missed it is heavy on my heart. Now I'm trying to figure out how to make the most of the remaining nights. Has anyone else ever been in this situation? Any advice would be appreciated, insha'Allah.
