Hi, I m 18 years old, for the last week I have been experiencing shortness of breath , twice I have woken up during the the night because of this, I am always tired, I literally feel like I have to lie down. Even though I sleep 8-9 hrs per night. A headache for two days that was easy to forget about until it got really bad for about an hour each evening almost making me cry. Nausea in the morning, loss of appetite, lack of concentration and lightheaded. Although my breathing has gotten better and headaches have become less regular, I am still very pale, I ve bags under my eyes, really tired and loss of appetite. If you could give me some advice on this it would be great, thank you.
