How can you tell the difference between normal hangover induced anxiety and alcohol withdrawal?

For context I’m 21F and have been drinking excessive amounts every weekend/every second weekend for about 7 months. I woke up yesterday after a night of heavy drinking to a pounding headache I’ve never experienced before when just normally hungover with just added symptoms like shakes/fever/panic attacks/brain fog which felt much more severe then any other hangover I’ve had. Once I calmed myself down a little the fever and headache stopped probably about 20 minutes after it initially started. It’s almost been 24 hrs since my last drink and I’m slowly coming round – shaking has eased a little and the headache has eased off but I’m still left with pretty extreme dizziness/brain fog and panicky feelings I have a history of panic attacks and I called the nurse on call and she didn’t seem to worried about anything but if I’m starting to feel a little better at almost the 24hr mark would this mean I’m going to go into severe withdrawals or would this just be a severe hangover? I’ve been told I’m going to be okay as I’m not a chronic everyday drinker just drink excessive amounts once a week/every second week but I still get these really panicky feelings and I’m not sure if the mild shaking and brain fog I have now is linked to just anxiety or if it’s something more serious or if I need to be a chronic drinker to start experiencing real withdrawal symptoms I don’t know if the symptoms I had earlier has triggered me to get panic attacks along with symptoms or if it’s something more serious
