Kids who looked about 5 years old were handed Kalashnikovs, and their mums were getting them to pose for photos with guns that were bigger than them! I could see that they were celebrating but it all felt wrong to see kids so young around guns. A year ago, few on these streets would have even seen a rifle. Now as I was deafened by the sound of anti-aircraft guns fired into the air in victory, it was clear that life will never be the same again for Libya. I smiled uncomfortably at the crowd as I was handed the new Libyan flag.

But that's just one country in a part of the world where things are changing so quickly it's hard to keep up – it’s the same in Syria. That's the Arab Spring for you.

I went to neighbouring Lebanon where I saw cyber-activists sit at computers watching video after video from Syria of bomb-hit homes; of soldiers beating people who say no to Syrian president Assad's rule and many people screaming for it all to stop.

I also met some of the people who call themselves the Free Syrian Army who were once part of President Assad's forces but are now fighting against him to the death. As far as we can tell, the fate of Syria lies in the hands of these self-appointed freedom fighters.

But, whereas the Libyans have got their freedom, reports say the Syrians are dying every day waiting for theirs. My Arab Spring journey has taught me one thing - that revolutions can be ecstatic and the best high you can ever know; but on the way they are also terrifying, brutal and murderous.

Riots and Revolutions: My Arab Journey is on Monday at 9pm

The second I landed in Egypt I could feel the buzz that comes with a million things happening at once: that feeling that my brain can't keep up with my eyes! This was a place where a real revolution had already happened; but when I got there, there were still protests going on against the Army.

My experience in the capital city Cairo was a rollercoaster ride. It started with just meeting a Facebook friend and ended with me in a riot, getting chased by the secret police! Standing there as the protesters squared up to the army, I was excited and feeling the rush… I was so naïve.

Stuck between the army (who I saw hitting anything that came their way with wooden sticks), and the protesters (who were ripping up paving slabs and hurling them at our heads), there really was nowhere to run. We got out of no-man's land just in time but I was shaking for hours afterwards.

Bahrain, the next country in my journey, couldn't be more different even though it had also seen major protests during the Arab Spring. Glass skyscrapers, paved roads and Starbucks at every street corner – it was a big change from Egypt. But the silence on the streets and shopping centres felt wrong. It was as if Bahrain had faced a silent and unsuccessful revolution; one that seemed to have been choked off before it could even begin.

However, I discovered that wasn’t quite true. I had to go to the small towns before I saw any signs of something happening. I saw graffiti saying "down with the regime" plastered on walls which had then been painted over by the police, only to be sprayed on again.

During one protest in a small town, the police started to take action against the protesters and then, started shooting tear gas at us. It was chaos; people running everywhere and the gas burning my eyes and skin. I got away as soon as I could but the Bahrainis stayed on the streets for hours. Why were these people being tear gassed? What had the Bahrainis done to deserve this? Were they armed and dangerous? No. From what I saw they were carrying flags and flowers and chanting for peace.

And although child marriage is illegal in many countries, it happens all over the world. One in seven girls gets married before the age of 15 in the developing world. Can it really be so bad for all of them, or is it just our Western perspective that makes it seem so shocking? That's what I wanted to find out.

I set off for two countries with some of the highest rates of child marriage in the world - India and Bangladesh. It was a gruelling trip through some of the poorest parts of south Asia - from the slums of Dhaka to remote villages in the deserts of Rajasthan. I found stories of despair, hope, and defiance. And the people I met completely changed my views about child marriage in a way I wasn't expecting.
