Dear Doctor, Hello, my name is Blake, and I am an eighteen year old male (almost nineteen years of age). I am supposed to visit with a doctor next month, but I thought that I would go ahead and get another opinion. My health-related question is that I am frequently tired, fatigued, irritable, and have a constant craving for food. I have researched these symptoms online, but especially due to my age range, I have found no definite answer. To me, it feels like in order to get relief, I either have to sleep often or eat something often. Also, I notice that I am irritable and will often become angry with my mom. I hate starting arguments, but it almost feels like I have no control over my temper. Sometimes, dizziness also accompanies these symptoms. Any advice or suggestions as to what it might be? I would really appreciate a response. My e-mail address is: YYYY@YYYY . Thanks, Blake
