I'm always tired, is there something i can do?

Yes: Visit your doctor-= fatigue has many factors, including lifestyle, diet, disease, stressors, exposure to toxins etc. Your doctor will help you navigate through the maze of possible causes by taking a detailed history and physical exam. He then can make a plan that is appropriate for you.

Yes: Make sure you are getting good quality sleep with correct temp in room, lighting, no physically or excessively stressful mental work prior to bed, no caffeine or alcohol in evenings. Do you snore? Have you had your thyroid and blood values checked?

Sleep: I'm sorry to say ... But without some more information, it's impossible to really answer this question adequately. However, the best way to combat being tired is to look at your sleep architecture and improve it.
