"I first noticed that I had purple dotted bruises on my feet and was starting to get more tired than I usually did. I was under the weather everyday.
"I remember that I tried riding my bike up the hill but I could not because I had no energy. I had bags before, so it was a sign of something but we did not take too much notice. We just thought I had not had enough sleep. And we thought my purple toes were bruises from football at the weekend.
What have I got?
"Then we went to our GP and he had a look at me and sent me for a blood test. I went to my dad’s but my mum rang and said I had to go back to the hospital urgently. They we are still saying not to worry.
"After more tests I was told I had leukaemia. I was crying for an hour – I couldn’t stop.
Off to hospital
"I went to hospital about four days after I was told. I was scared then. I went in an ambulance all the way to London from Southend.
"At that time I did not know anything about Great Ormond Street Hospital (GOSH). I did not know much about it but there was a lovely lady who made me feel better by explaining what would happen and going through things.
"I did not want to start my treatment straight away because I was scared and worried about losing my hair. So they left it for the weekend. They let me settle in for a few days.
Treatment and intensive care
"I had four lots of chemotherapy
over five months. But I also spent one month in a coma in the intensive care unit with a yellow space helmet thing on to increase my blood pressure so that I could breathe easier because my lungs were bleeding.
"Do not worry, that doesn’t happen to everyone with leukaemia but I got ill.
"I slept for a month. I did not know anything about it but that was the best way. That was a horrible time for my family, or any family.
Out of intensive care
"Thirty one days later I came out of intensive care but I was not waking up. They did an MRI scan
while I was still asleep. They spotted this goo in my head. They did lots of tests to find out what it was but they came back negative.
"I had to have an operation on my brain – they took some ‘goo’ to see what it was so they could decide what treatment to give me. I went back to intensive care but I was alright and I had survived the operation.
Positive mental attitude
"When I woke up I could not move anything. I could only blink. I had to do physio
every day for nine weeks. I hated it at first because it was hard.
"I had to have a break from chemo to get stronger. The physio went on and gradually, towards the end, it went down to every two days. I surprised them by how quickly I got better.
"I would not be out that hospital now if it was not for the determination of my family. We stayed strong and got through it.
"I left the hospital in August after five months. My life is back to normal now and I can do every sport that I used to. I am eating properly and I am back at school.
"Having a positive mental attitude – that is what gets you through it. Be brave and courageous."
