Art....?

I've hit a bit of a cross roads in my life recently... Do I really like art or do I just think that's all I'm good at..... I don't know if art really makes me happy. Honestly I never really have a desire to just, do art. It's hard. It takes time and I don't have the patience. If someone tells me I have to do it I'll do it but other than that I don't really just go at it drawing. I doodle yeah, but realistic no. I want to do realistic stuff but what really makes me happy is drawing fun creature things, so now I'm curious.... What if instead of Biomedical art I did video game concept art..... I don't know. I just want to beat my head in just drawing things that u can just see. Imagination is just so much more interesting, but would I be cut out for that..... Or do I want to do something entirely different........ I don't know... Any suggestions? Please help, not a lot of time left to decide anymore....
