How to deal with waking up with anxiety?

I used to have anxiety on a daily basis a couple years ago but I helped myself through it and haven’t experienced it as much in recent times. But I’m starting to wake up in the middle of the night and I feel very anxious. It’s happened only twice so far but twice in a row and it’s a new feeling. I do my usual night routine that’s relaxing and calm. I sleep away and wake up about one hour later and feel so anxious. My heart rate becomes higher, I feel numb and tingly, nervous and as if I can’t breathe properly. Tonight I took a valerian root supplement for calming me down and it’s helping. As I’m typing this I feel calmer , But I’m concerned and don’t want this happening again. After waking up I can’t sleep again and then during the day I feel so sleepy which makes me feel lightheaded too.

Any advice or tips will be helpful, thank you!😊
