I’m 21 M and for the past few weeks I’ve only been able to get 4-5 hrs sleep a night no matter how tired I am and even if I don’t take naps. I already have pretty bad cardio phobia and this makes it even worse to deal with as it makes it harder to take those extra steps like going out or trying exercise. At this point I’m not sure what to do because I’ve tried occupying myself during the day and avoided naps to get the longest sleep possible at night however the maximum I can manage is 5hrs. Any advice?
