Am I wrong?

Am I wrong for wanting to go home to tend to my old disabled dog with separation anxiety, and to my bed….after spending 3 days walking around a convention center, instead of being at a loud after party with alcohol and raving? I don’t drink, and I don’t wanna dance after walking on my feet for 3 days through an enormous convention center full of people. I mean, I get it. It’s my boyfriend’s birthday. He can do what he wants. I have no problem with that. But for everyone to get upset with me for not wanting to be here when it’s not my scene….it just doesn’t make sense to me. My friend got us into this place for free…but no one asked me if I was interested. Sure, I like being included. And maybe I would have been offended if she had gotten everyone else in but me…but…I was basically volunteered to go. Maybe I shouldn’t complain and be grateful for them wanting me to come along. However, I’m actually tired of being volunteered. I’m not a child. I’m an adult, and when I speak my mind, it feels like they get offended that I don’t wanna do what they wanna do. And normally, my boyfriend isn’t the dancer type. But he’s in this rave party, drinking and dancing in his late almost tail end of his 40s. Good, he’s having a good time. More power to him. But it’s almost midnight, my dog has been howling since before the pet sitter left, and has probably already left messes on the floor and walked in it since he’s got no eyes…and my head and feet are killing me. I don’t mean to complain so much, but have no other outlet since my friends are just gonna come down on me for being such a downer. I don’t mean to be. And I’ve been told my anxiety gives others anxiety. Maybe I should just disappear if I’m not supposed to express the way I feel.
