Help!! How can I find out if I can really sing? I don't want to be one of those

Question:

Help!! How can I find out if I can really sing? I don't want to be one of those people with false hopes.?

I attend a conservatory for voice. I am being trained in opera. I don't know if I truly have the talent to become successful in the future. Should I put a video of myself on youtube to find out? Some people give you compliments just to be nice. I need a reality check. People have said that I have a beautiful voice, yet I have doubts. To their ears it might sound good, but what about in the real world. Do I have great talent? How can I find out?
