Weird questions incoming^^

... How do you guys feel when you go to a club alone? I come from a place of social anxiety and I notice that not having friends to fall back to makes me feel like I'm being watched, meaning I feel like I can't just walk up to a girl because I have no "momentum" or whatever. When I'm out with others I can barely bring myself to do it tho. If you understand the problem I'm having: What kind of specific behaviour would you recommend to feel more natural when out alone? Dancing without a drink, standing with a drink, sitting with a drink? Approaching while taking a round through the club, or just from my "base" position?
