Can we talk about a situation where it’s okay to cope with alcohol?

Like okay I get it.. if I drink every time I get stressed that’s alcoholism. If I drink through major life events, that’s not healthy.. but like fuck, I’m currently in the national guard, a server at a restaurant, and a year round college student. I didn’t get off work until 2am tonight and I watched a dude fger his girlfriend under the table while I took their order today. FULL VIEW. Can’t I just drink to deal with this shit sometimes? Is this unhealthy? Everything in me says I’m gonna be like dad one day if I drink after a bad day of work but fuck… he fgered her… at my table.. to completion..
