Is getting blephorplasty really worth getting done to pursue my acting career? I'm 19?

I am 19 years old I just turned 19 on April 7th. When I look at myself in the mirror and act.. I don't look serious and my eye lids just turn big all of the sudden. I don't look like a girl that would be a professional actor someday just cause the way my eyes are and more. My eye lids are perfectly fine but when I don't kinda squint I look like I'm high. But I have never done a drug in my entire life. Acting is my dream and passion and I really wanna reach my dream someday but I don't want my looks or eyes ruining this for me. No make-up works either. I don't have fat in the eye lids or anything they are just kinda droopy.. Weird. What should I do? I'm scared to get blephorplasty cause I'm scared I might ruin my eyes. Do you really have to be pretty to be in acting? I'm not calling myself ugly or pretty
