Is it too much to drink every night at 19?

Im 19 years old and lately I’ve been drinking every night. Most nights I’ll just crack open a cooler and not even finish it as alcohol makes me sleepy, but when my friends are in town we go out a lot and i get pretty drunk. They drink too, but mostly smoke a lot of weed. I can’t smoke weed due to a dark period in my life at 17 where i began to abuse substances and ended up with HPPD for about a year. Around that time I went completely sober and didn’t even drink, which really sucked as i was fresh out of high school and all my friends were drinking and partying. I began to drink again about a year ago, and I’m very careful to not do it when in the wrong frame of mind to avoid using it as an unhealthy coping mechanism; ie, if I’m feeling depressed or anxious. However, I generally do struggle with severe anxiety disorders, including social anxiety, and when I’m out with friends and overthinking every interaction I find that alcohol eases that stress, which I’m aware is not necessarily healthy. I guess what I’m looking for out of this post isn’t a cut and dry answer, but more so just other people’s advice based on their own experiences. I’m overall happy with how my life is currently. I have a stable job that I like, I’m majoring in something I’m passionate about, I have good friends, I have a supportive partner, and I have my loving family. I don’t want to go back to unhealthy coping mechanisms.
