Drinking alcohol to forget/during bad times?

I recently noticed that they do that a lot in movies where alcohol is not consumed on social occasions with friends and to have a good time, but the opposite. You had a bad day at work, you had to deal with stuff or let’s just say you feel bad/guilty about something so you resort to alcohol. You drink to forget or to ease the pain basically. I don’t know what’s the point really to get wasted or just a couple of drinks but they are awlays pushing this agenda in movies and in my opinion alcohol doesn’t work like this in the real life. If you drink alone while you are depressed, you will just get more depressed. I am curious to hear different opinions on the subject.
