Fiona's shocked face was splashed across the newspapers

Fiona Trueman was in the carriage behind the Piccadilly Line suicide bomber Germaine Lindsay

As the train pulled out of Kings Cross and headed towards Russell Square, his bomb went off, killing 27 passengers.

Here she tells Breakfast's Ben Bevington how the events of that day changed her life:

Getting on the second carriage rather than the first was ultimately a life saving decision. I do feel bad sometimes. I think why was it me that survived? Why does someone else deserve to die not me?

The first few weeks after July 7th were awful really. I was on an emotional roller coaster, one minute feeling really guilty, the next feeling so happy to be alive.

I found it very difficult to adjust back to going to work. I had problems with short term memory loss, exhaustion.

I still get nightmares.. They can be about other terrorist plots, planes crashing into London

I used to drive to work and spent three hours in the car every day crossing London. Now I have a job that's a ten minute walk from my house in St Albans.

I realised that work shouldn't be my number one priority and that family and friends are the most important thing.

That's one of the first things that entered my head when we were trapped down there. 'Oh my God I've never got to have children, I've never got be a mum.' It's definitely made me realise I want children.

Flashbacks

Whenever I hear sirens it sets off a trigger in my brain and takes me back to Kings Cross on the day and being outside amid the chaos.

I constantly look around at who's on the train.. And if I feel uncomfortable I have to get up and move to a different carriage. I wish I didn't have to, but your body tells you have to move.

And if someone bursts a balloon it makes me jump. I usually screech or scream - they don't understand why I'm so jumpy.

I still get nightmares too. They might not even be about being stuck on a tube train. They can be about other terrorist plots, planes crashing into London, and running around the city and trying to dodge crashing aeroplanes.

I come into London probably about once every couple of months for work. It's strange thinking the bombers came in from Luton on the same line - I was on the train behind them on July 7 too.

I constantly look around at who's on the train, look if people have got big bags or not. And if I feel uncomfortable I have to get up and move to a different carriage. I wish I didn't have to but your body tells you have to move.

Taking the tube

I first went onto the tube after July 7th in about October. I went with a very supportive friend but it was very nerve wracking. I made sure we sat opposite a mum and her young child because I knew that if I had a little girl looking at me I wouldn't become as emotional because I wouldn't want to scare her.

As we went into the tunnel it was awful; there was so much adrenaline running through my body and I was shaking like a leaf.

In an ideal world, I'd like to get to the point where I'm not thinking about 7/7 every single day.

I have been on the tube twice by myself and I really thought I could do it. I was really brave.

Unfortunately as soon as I started hearing the metal screeching of the tube noises I just couldn't do it. I had to put my fingers in my ears, and I shut my eyes. It was just awful. I had to get out at the next stop.

Another time, the tube stopped in between stations. That was my worst nightmare - I was having a panic attack and breathing heavily and shaking.

Moving on

The anniversary has made me feel slightly uneasy again but I think as soon as it's passed I can really only look forward.

In an ideal world I'd like to get to the point where I'm not thinking about July 7th every single day. There's a part of me that will never forget the people who didn't make it but I definitely want to move on and seize every opportunity
