Sprained ankle but afraid I broke it?

About..two weeks ago I fall off a chair..Only on tuesday did i go to hospital. The said they couldn't find anything wrong with it but i think they were lying to me as they have done it before. I fractured my finger and knuckle and the hospital said that nothing was wrong with my finger..my finger was still giving me pain so a wekk or two later we went back and they told us that it was fractured. They never showed us my x-ray of my knuckle and finger. When i broke my wrist they showed me straight away, pointing out why they were giving me the cast and stuff..But with my ankle they have done the same again and not showed me. They told me that it was a nasty sprain and something was sticking out where it shouldn't be. The nest day i could put weight on my ankle so i thought it was all good. At school we had a FLD (flexible learning day) where we dont do any of our lesson we do something totally different,,And the theme of the day was fitness and exercise. I had been to a teacher that morning saying i couldn't join in with any of the activites. The teacher said fine and was suppose to give me another timetable..They didnt, So i went to the dance class i was suppose to be doing.. Street dancing. I thought cause i could but weight on my ankle and it didn't hurt this will be fine, I can do this. Half way through the lesson something happened to my ankle and me and my two friends heard a kind of clicking/cracking noise. It was painful to walk on. But i still carried on with my lesson because i didnt want to feel stupid leaving the lesson. So i continued with the lesson. After the lesson I limped to meet my other friends one of my friends hit the nack of my ankle and I bursted into tears. I went to the canteen and sat there crying some more. My boyfriend offered to carry me to the reception.But i walked. The lady had a look and said it looked swollen and very badly bruised. She sent me home saying i have to rest it for four days. Im still resting it now..But its painful to walk on and my big toe hurts alot. I hit it off the door this morning..me being clumsy..and i heard another cracking/clicking noise. My mum said after resting it for four days we will she how it is but she wont take me back to the hospital because i was only there the other day..What can you do to help me?? I know i was stupid to go to the class after the hospital said to rest it and stay out of all sport activities..sorry..
