Anxiety spikes

I’ve been having a weird anxiety spikes, for example I didn’t sleep too much last night because I would wake up and lay awake with that stomach drop feeling over and over again but my mind isn’t panicked over anything or worried about anything other than my husband who starts his first day as a police officer today. But my mind isn’t PANICKED about it, just the obvious worry one has with a loved one in that line of work.

But my body is giving me an anxiety or panicked response and I don’t know what it is or how to combat it.
