Should I be a comedic actor?

Ok so I'm not so great at standing out, but I watch snl and improv shows and just have this feeling... like.. that's what I want to do. I might not be the next Tina Fey or Amy Poehler but... what if I could be... I'm 15 and I'm thinking about taking a intro to acting and intro to improv comedy cl but I don't want to necessarily do it just because it looks fun... I see some people do stand up like Aziz and they just act like psychos... I don't know if I could ever be I don't know that free.. not caring what anyone thought and just made people laugh.. I'm funny, don't get me wrong I've been making people laugh forever but I'm just not good on the spot... it's hard to explain. And when I really think about it.. writing/ acting for a living... it's just the only way I see myself being actually happy and knowing if I died tomorrow I would be satisfied with this life.. And I would only want to do it if I could live it out to the fullest. I'm not the best in front of people I think it's just my confidence level is really low.. will I become comfortable and be able to act one day??
