Is this a hangover? Only drank 1 drink per day, anxiety/jitters not gone after a week sober.

I got into the habit of drinking 1 glass of wine per day in the past few months, but decided to stop. I noticed I’ve been jittery, agitated, and anxious after stopping. The thing is, it’s been a week, shouldn’t the hangover be over with after 1-3 days? I was drinking the wine to cope with anxiety, so I’m not sure if this a withdrawal/rebound effect.

The only reason I’m asking is because I want to rule out other conditions.

I’m going to continue not drinking and hope it goes away after a few weeks, but I don’t know if the alcohol is what caused this.
