Should I Become an Actress?

I believe that the last part of your statement should answer it.. .If you love it do it. I've learned for the past couple years to always do something that makes you truly happy(it would seriously save your sanity). There are always opportunities for EVERYONE so physical appearances shouldn't matter. But if you ever face rejection, do not ever let that get in the way of your main goal/love ...acting. About the classes, it is very crucial for an actor to have some type of training but in the meantime you should audition for plays and when you get in use that as your temporal training until you have time for actual classes. Learn from everyone in the field and even intern for a theater or an agency to get the inside scoop of the industry(of course when you have time). GOOD LUCK!!!
