23y old heavily drinking

Like the past month i’ve probably had 150+ beers a week, completely dependent on alcohol to sleep. I know I need to quit but i’m scared of any withdrawal symptoms. Ive quit for two days and ive felt anxiety, depression and a very fast heart rate, and it seemed to go away when I had a drink. I need advice to avoid any shakes or extreme withdrawal symptoms, drinking right now but I don’t know how to quit, any advice would be appreciated. Dealing with a lot of personal issues and getting fucked up has been my solution for a while now
