Weak , tired , in pain all the time

Hi . . . I'm 17 and I've been experiencing extreme body aches . I have neck , back , shoulder , knee and hip pains and my legs feel as if they can barely carry me . My muscles and joints hurt a lot and after I've walked around and I go to lay down it feels as if my ribs are crushing my lungs . Also , I'm really tired all the time , I feel like all my enegry has been sucked dry . What might be wrong ?? And how can I get better because I honestly can't live like this anymore :(
