Hello everyone. My body has been acting weird lately and they are showing weird symptoms that don't seem normal. I am 14 and a well developed girl. So first, my sleep. My sleep is often disturbed and empty and about once a week I wake up from a racing heart and out of breathe. I don't have night terrors, so I found this odd. Here are some more things that are bothering me. I can't concentrate, My memory is getting worse, my breathing has made strange high pitched noises for two months and is shallow. I feel like air can never fully fill up my lungs.(I don't have asthma) Also I have quick mood changes and reckless behavior. I'm not on any medication, I don't drink or do alcohol and again, I am only 14. Please help.
