Signs of depression

Patient: Hello, I am 18 years old and I started having lots of fatigue, so I’m always tired. At times it feels like I might snap out of it but nothing happens and I remain the same. This just started about a week ago, I haven’t been happy since. Best feeling I can describe myself right now is empty. These feelings just started last week which is really confusing. I did some research on alexithymia and the symptoms for it sound about right to mine.

Symptoms: depressed
