I Have Been Laying In Bed Trying To Sleep For

I have been laying in bed trying to sleep for about an hour now. My heart rate seemed faster than normal so I checked it out and got 84 beats a minute. Is that bad? I am an 18 year old male. Work out almost everyday for about an hour or more and I also play baseball and occasionally basketball. I do take pre-workout, 1000 calorie protein shakes (2 a day), and 10g or creating a day.
