So about a week ago my hand started shaking really badly and so it's been like that for one whole week,everyday, so my mum decided to make a appointment,the GP was checking things like reflexes and blood pressure.At the end I think she had no clue what was causing it,especially since I'm having a tremor at the age of 13, so she told my mum later on that I should go get a blood test.0-0 Which I've never got before and that's manly what it is.I wanted to know the possibility of what it might be just in case you know,cos I have know Idea as to what it might be.Also the arm they're taking the blood from is my left and I've got some self-harm scars there so I was also wondering is there any way of hiding them my mum will be coming with me. :/ problem..
