Chronic neck pain. Help and suggest.

I'm having neck pain for the past 6 years. During my college I used to study lying on the bed on my stomach and supporting myself with my elbows. Over time I realised that it started putting a bit of a pressure on my neck and elbows and I started to get pain in the neck and the elbows. I also used to ride for 2 hours everyday with a slightly heavy helmet which also added to the pain. Now that I'm working and I don't strain myself much the neck pain is only getting worse. My neck feels stiff these days. It hurts really bad when I bend down or look up. I'm not able to touch my chest with my chin. And I always feel as though my neck is locked in one direction and I get a strong urge to release it by turning the neck in the opposite direction. When I trying rotating my neck I'm clockwise direction I feel my head to be heavy on my neck. I'm really scared. I'm unable to work long hours & pursue my hobbies. I get pain in my shoulders and neck when I lift heavy things. Please help and suggest.
