Introducing myself to the class !

I am starting school in a week and I know that the teacher will let make me to introduce myself in front of the class.  As I don't have a very good level in my English is poor, I need your help : )

So please correct my paragraph : self-introduction.

Since this is going to be a semi-formal self introduction, the wording will be different than one that is meant for an essay.  Opt for shorter sentences in speech.

Hello everyone,

I'm Sarah.  I'm 16 years old. I'll turn be 17 next January.

I raised in a family of dorctor My family is a family of doctors.  and therefore  So it's obvious natural for me to that I really love like science and everything on about human biology corp.

I've got 2 brothers and one sister. that I love them more than anything. Each one of them are pretty special and unique. I also have awesome many good friends whom I can always count on.

I really love enjoy cooking, reading novels, l studying language,s, traveling and discovering the whole wide world.

 
I'm a hard working student. I always try to do the my best of myself .

I have plenty of many dreams. I remembered that when I was little child, I wanted to be a the president. , but Now this dream seems ridiculous. Now I want to be a good doctor.

I do hope that we'll have spend a great year together!

That's all it ! [You can say something funny here, like "I wanted to say more but then I'm afraid that I will bore you all to no end!"]
^^ Thanks
