Depression affects people in different ways.
I myself have been through it. At first I didn't know I was depressed.
I have had a condition called Hydrocephalus since birth which is an aquired brain injury. This is also known as 'Water On the Brain'. The Hydrocephalus is controlled by a tube. Mine is near my neck on the left side and controls the cerebal fluid.

This condition caused me to have horrible headaches and because the 'Shunt device' was blocked not allowing the fluid to drain properly I was being sick. Also the short term memory takes a long term to repair itself. But the funny thing is, in my experience my long term memory stayed the same.

I remember it quite well, I was taking part in a Christmas play with my 'Cubs group'. I got through every performance and then shortly afterwards I was in my local childrens hospital.

Anyway I was admitted to the childrens hospital, I can remember being in my mum and dad's car, it was dark and it was like my head had a rock on it that I couldn't move. Luckily the childrens hospital wasn't far to get to.
So it was agreed that I had to have an urgent operation to have my shunt extended. Because this would make the tube a bit longer to help control the fluid and free me of any more regular headaches. The shunt itself looks like a wire or a cable. Things were made worse because it took a while for the hospital to get me an available bed.

The operation was a success, but my problems were about to continue.
It's debatable as to whether I fully recovered. My short term memory had become impaired, and it took me several years, maybe around 2002 for it to have gained a bit normality.
1998, was the year I or my mum and dad had to choose the right senior school. I always thought i didn't get to choose. This caused me a lot of anger and frustration. But mum and dad I think were talked into choosing this school, because the junior school headteacher knew there were some from junior school going there.
The problem was they were bullies, and I had to move from my first class to a new one. Thinking it'd solved the problem, it continued. Because there was another one from the same school causing me more crap.

As time went on, the teachers failed to come to a solution with my mum and dad. Obviously I was upset, but in the end I defied the bullies and I became more aware of myself and I didn't let bullying beat me. The school basically misunderstood my brain injury. The thing I couldn't comprehend was that they understood other disabilities that the other students had.
There were countless meetings. Some I was present at, some I chose not to. I'd got fed up basically.

Now I'm almost twenty nine years old, and I have progressed massively.
I now have the confidence to do fun things, normal things like watching my favourite football team, exercise, photography, blogging, watching movies, music concerts and I have an amazing understanding girlfriend who accepts me for who I am. Because of my disability from when I was younger I felt like I didn't 'fit in'. But I've learnt it's not about that. You have your own unique style, and that's what I have. You don't have to be like everybody else.
