What to do if i cant sleep at night because im worried about my future and absolutely terrified of the fact that i wont make it. (i put this under health because i dont think sleepless and stressful nights are healthy...)

Asap during the past few weeks or months, have you noticed any exercises that have become too easy for you? do you think you need to increase the intensity in any of the three exercise areas in your workouts? evaluate your exercise progress in the three exercise areas (cardiovascular, resistance, and flexibility) and list what modifications, if any, you may need to make in your exercise routine.
