Do I have sun poisoning?

Okay so yesterday I was outside for like 6 hours and I didn't put any sun tan lotion on. I'm pretty pale, and that was my first time actually going in the sun for a while. I have the worst pains ever. Yesterday when I came home from the beach, I cried for like two hours non stop because the pain was so bad. I felt nauseous, dizzy, I had a 100 degree fever, I was both hot and cold. I legit have sunburn all over my back, stomach, legs, and shoulders. I can't even move my legs, so I've been laying down all day. I tried to take a shower today and when I got up I felt like I was going to throw up. I honestly feel like I need to go to the hospital or doctors asap, because I can't deal with this pain. My parents think that the hospital won't be able to do anything? Do you think I should go to the hospital or doctors?
