I Need to figure out what to do with this drinking problem.

I’m 18 year old male, have several major mental disorders and multiple attempts. I’m an addict for anything. I was diagnosed with cannabis use disorder and addicted to that for 3 years and finally dropped it. I started drinking as soon as I turned 18 and could buy it, slowly over the course of a year it’s ramped up in the amounts I drink. I don’t think I’ve been sobre for the past 3 months now. I like to drink wine and hope it won’t kill me as bad as hard alcohol. The past few weeks I’ve been drinking 1-2 bottles of a wine a day on average some days a lot more plus several shots.

My question is how long + How much alcohol do you need to intake to start feeling withdrawal if you stop? I also take 150 mg of seroquel and 60mg of vyvanse daily.
