Help me 😬

Madison
So I play 3 sports, two of them are in season right now, but the issue is I am always exhausted, I never get any sleep. I go the bed early but never fall asleep until 3 or 4 in the morning, and I don't have any electronics in the room so it can't be from the blue light keeping me up, and I take Benadryl to knock me out but it's never woken so I stopped recently, my cousin thinks I'm anemic because I have an irregular period and I'm cold 24/7, but my mom thinks I'm fine, but I'm not so sure anymore. The main issue I'm worried about is not being able to sleep because it really effecting me when I play sports. I'm playing volleyball and running cross country right now and you can tell the lack of sleep is effecting both, I'm sluggish on the court and can't move as quickly, and when I run my times are slower than they've ever been. Any help would be appreciated.Â
