How can I not feel so extremely tired and dead every single day?

When i get out of bed I can barely open my eyes, I put all my effort every day just to stand out of bed and get on with my day. After I get out I'm ok, but during the day I still don't feel very alive, not very energetic, and feel like the bored feeling. It's been like this for around 3 years. I know my lifestyle isn't the healthiest, and my family is very stressful, my parents and I aren't very close making it worse. I don't remember the last time I was able to have a smile on my face and have actually mean it. Please don't say depression, for various reasons, and help me find a way to get my life back straight.
