The thing about mental health issues is this: you and others can't see them.
I remember when I was at my lowest point with anxiety. I remember thinking: “If I break my leg I can go to the doctor and he'll fix it. If I go to the doctor and tell him how I feel, they might never understand what the real problem is.”
I first showed signs of bipolar disorder at the tender age of 17. Family and work colleagues knew that I was not myself but could not understand what had happened to me, so my mum encouraged me to visit the GP. Sadly, he misdiagnosed my symptoms and assumed I had anxiety and depression. I then commenced taking antidepressants.
Having gone through difficulties myself during my time at university, I was hugely helped by my housemates who provided a formidable support structure to help me through tough times. Throughout my time at university, we all helped each other with a number of things. We were very close and could speak, share, and discuss pretty much anything. This environment helped a lot.
