Alcohol withdrawal

So I’m 23/f 140lbs and have been drinking about 6 drinks a night for maybe 3 months a little bit less. I started doing it to sleep after nothing was helping me sleep. Well now I’m tired of shifty sleep and hung over mornings. I haven’t had a drink in about 14 hours and experienced the normal shakes, upset stomach and sweating. As the day is going on it’s not that bad but I’m worried it’s going to just randomly get worse. What’s the likelihood that I will have extreme withdrawal symptoms? Before this I didn’t drink for 9 months. I’m worried of hallucinations and seizures
