TSS?

I think I have TSS . Started my period Saturday and just used liners bc it was light. Sunday mornin it was normal so in put in a regular tampon. I changed it about forty five minutes later and it had about less than half full. I had been changin them about every hour with not much on them. Then Monday I changed about every one to two hours and not much on them. Well yesterday i put one and took it out straightaway because it wasnt in right and it hurt trying to get it out it felt stuck, wi h it neer does, and just wore liners all day. About an hour after that, I started feeling weak and tired, and I wOuld get slightly dizzy when I would get up. Then for about 30 seconds, I had a slight headache. About 8 pm that day, I had a slight ache in my shoulder for around 30 secs. May I add that I had felt weak and somewhat chilly and tired ever since. An hour after the first tampon that day. Today I woke up and been weak and tired. I got a cold water to drink and immediately felt nauseous after that for about a minute. I went downstairs and On the way up, my legs felt burning in my tibia and fibula. Also my ankle hurt. Now when I move my leg it burns slightly. Also since yesterday my thought has been just a tiny bit sore when I swallow. May I add, I had diaherra twice yesterday.
Do you think I have TSS and what should I do? I'm 14. Thanks
