Adolescent Psychiatrist Questions Somnolence

What could cause a constant state of somnolence?

I feel tired all of the time. Even after waking up from a full night of sleep- I always want to sleep. During the day I have a hard time pushing through my tasks. My primary care doctor ran a ton of blood work, CBC, CMO, thyroid panel, etc. Everything was perfect. What causes somnolence, is it a physical or mental problem? Are there any treatments? I am tired of being tired!

The severity of your somnolence sounds more like that related to a sleep disorder such as OSA (obstructive sleep apnea) than to a mental/psychiatric disorder. Sleepiness due to the latter is milder and varies throughout the day. If your primary care has truly ruled out every possible physical cause for your excessive daytime somnolence, you may benefit from a sleep study. In addition to OSA, there are other sleep disorders that can prevent a person from getting sufficient restful sleep, and there are wake-promoting medications for patients in whom they're appropriate.
Common conditions causing somnolence that would not show up in blood tests include sleep disorders such as sleep apnea and restless legs syndrome.
Depression, stress, over work, and just getting older can cause somnolence.
Well, it’s always hard to answer certain questions right away without seeing in person and talking with someone, but depression can easily make one tired all the time and we can be depressed without even knowing it, so I would have to say it can be depression.
