Looking back it is incredible how in control (the anxiety) was. It was kind of difficult dealing with that and trying to maintain A* performance."“Looking back, I realised I was really anxious. I was diagnosed with general anxiety disorder. Sometimes it was social issues, getting very anxious about doing particular things; I didn’t go to PE for some reason for many years.“But then I went to college and it really helped me. I was treated with more respect, I felt like more of a person rather than someone who was able to get good grades.”Lotte Gleeson – I know the solution to the trolley problem… | Facebook Lotte will head to Oxford next month to study physics after getting A* in maths, further maths and chemistry, and an A in physics.And she is determined to spread the message that mental health problems should not hold students back.She said: “At school I didn’t think I had the ability to be able to go to university at all, let alone Oxbridge.

You can get better.”An inspiring message from an inspiring individual.
