How long will it take for my eyelashes to grow back?

Do they even grow back? I was part of a performance last year and I had to wear a boatload of make up which included liquid eyeliner and mascara. After that, the eyelashes on just my left eye started falling off and now my eyes are all.. uneven! I used to have long, thick, curly eyelashes but not only one eye has long, thick, curly eyelashes! Is there a way for me to get them to grow back faster?
