Drinking every night is it Alcohol withdrawal or panic disorder?

I’m a 23M I’ve been drinking since I was about 16 just drinking when I could get my hands on it because everyone else around me was doing it. I’d drink every Saturday night and get drunk and possibly a tall boy on Sunday to take off the nifty feeling. One night in 2020 I was 19 and drunk and me and my girlfriend at the time had an argument and we broke up, then the local store didint ID me so I had a way to buy beer and get drunk every night and this happened until December when I got a Job and cut back on my intake every night then I landed another job and drank the same amount but would still get drunk asf on the weekends, my dad passed in June 2023 I went into a deep depression and quit my job and I’ve been staying drunk every night since and then my brother passed in October of 2023 that’s when the anxiety and panic set in, I drank an energy drink while driving to Walmart 20 miles away when I had a full blown panic attack and thought. I was dying then I got on doctor google and it told me I was having alcohol withdrawal and I could have seizures and hallucinations so now I’m scared to quit and it’s hell to even drive anymore what are the chances I could have those bad withdrawal symptoms?
