hospitalized part 1

When I went to the emergency room they inserted me an IV. And after a lot of waiting, a sonography and that several doctors checked on me they decided I had to spend the night in the hospital.
I was really scared because I thought I was going home that day and even more frightened as doctors didn´t know the reason why I had that bump.
I remember I was in the temporary bed with my dad and another doctor came and told me they were going to send me to the second floor. They made me take off my clothes and get dressed with the hospital robe.
When I arrived I discovered my roomate was a really old lady. Unfortunately she shouted at night and she wouldn´t let me sleep. I remember sometimes she asked me to help her to wake up at which I always responded that I couldn´t.
The first morning, the team of doctors came to see me. They told me they did not know why I had that bump and that they would make me some tests to find it out. They told me the would do several tests on me:
-a biopsy of the bump to study it.
-several blood tests
-a scanner of my body in the hospital.
-punching my bump to analyse it
-a sonography
-mantra 
Afterwards I was really scared because I knew the biopsy will involve an operation. And I had never had an operation before. I was also supposing that some of the tests would hurt. I remember I cried a lot. I did not want to be that sick... I thought I would go home soon.
