What are some legal alternatives to alcohol for dealing with anxiety and depression?

Without alcohol, I’m too scared to talk to anyone.
I look fine, but without a drink, I can’t even meet someone’s gaze.

I’ve had five relationships, and before every date, I’d knock back 400ml of vodka plus six gums.

Guess what? THE GIRLS FUCKING LOVED IT.

The relationships didn’t last, though I never had a job, but that’s a different story.

How we doing drinkers? I went through 2 litres of vodka over 2 days. Woke up this morning in a pool of sweat. For a moment I thought I'd actually pissed myself, which isn't unusual for me during a binge, but fortunately it was only sweat. My right arm was completely numb, and I had a moment of complete panic thinking that I'd had a stroke in my sleep, but it turned out that I only slept on it, and the feeling returned after 30 seconds or so.
I spent the next 30 minutes in a state of total anxiety, before I finally decided to go to the shop and buy more, because I knew I wasn't going to handle this by myself. It's been several hours since then, and I've got a nice mellow drunk going on. Brain is slowed down, it has been sufficiently fueled with the alcohol it craves.

How you guys doing?

Does no one else find it strange that there's only one psychoactive drinkable substance which we can use for years without dying? Shouldn't there be a few, or even dozens, given how long the earth has existed. This strikes me as a lazy input from some higher power, either God or the creator of this simulation.
