If you want to go, just go.
You don't need the opinions of random people on the internet to reassure you.
There's not a single person on Earth who's opinion on what is and isn't normal is valid, worth a damn, or matters in the least.
I see so many people worrying about 'is it normal' - it doesn't matter, 'normal' doesn't exist, it's a totally insane concept.
I've been to clubs on my own, because I enjoy the energy, and had a good time. If God himself disproved of that, he can blow smoke up his holy hole; it's your life, you do NOT need others approval to live it.
