Sounds like you might be working out too much. Do you ever take a day off? That high resting heart rate may indicate overtraining. Also, how's your weight? There could be other things going on to. Have you had any blood work done. Could you be anemic? Hope things work out.
The rate is too high in my "book". Even at your young age aerobic exercise that puts your heart in the range of 185 is pushing it, maybe too much.
You didn't mention any rhythm irregularity, nor what you HR history is, i.e., was it at 60 in past years when at rest? Or, has your HR always be in the 100 range at rest?
