New to drinking, why do I overthink myself out of getting drunk

I’m 23, have never been drunk but have developed an interest in being able to drink socially. Every time I drink, I have 1 drink whether that’s a beer or a mixed drink. I end up getting anxious and nauseous almost immediately after. I have a history of anxiety and making myself nauseous for no reason so it’s nothing new. Has anyone else experienced this when starting drinking? Should I just drink past it and it’ll go away?
