Confidence, whats going onn?

Ok so I'm on my phone, so its gona be decent but excuse any weird randoom punctuation and spellings. Basically, I'm not shy or anything and I'm not the girl dancing on the table. I do drama and now as time progresses u have to be really loud and sorta not care about others around u. Icant do that atm? Does anyone know how icant care about others around me,coz I love actin,its just I can't stay in role wondering if someones bored, or something! I think its cause of the boys or something? Oh and I know I sound a little childish asking this.but I'm a teenager, ofc I'm gona sorta care? But ahh. Any advice guys? X
