I don’t gravitate towards drinking when I’m truly depressed?

I discovered alcohol not too long back and found it as my happy place because it made me feel invincible and overly confident (I’ve had confidence issues my whole life). I no doubt have also had depression and anxiety in and out my life too where periods of time I can’t eat or am basically bedridden by it. Now it’s one of those times and when I drink I don’t feel anything close to what I felt when I first started drinking, just fuzzy and warm at best. Why is this ?
