Emma has bipolar disorder and first became ill when she was 14, when she began to self harm and even attempt suicide.

She describes how she felt isolated when her friends were judgemental towards her, while her teachers would not take her back to school because they were worried about "contagion".

Now, three years since she felt better, Emma tells The World At One she is "definitely on top of everything" and able to deal with "ups and downs".
