Sadness?

I have to ask you guys how exactly you get sad from alcohol? I’ve drank alone and in social situations multiple times and I do not feel that feeling. What is it that makes you sad? Do you remember sad things? Do you imagine sad things? I’m genuinely curious for everyone’s input. Also, stay safe. If drinking makes you sad, anxious, depressed, or even if you’re drinking too much please slow down. Someone cares about you and you should care about yourself. Always. Thank you guys for any advice.
