The source of my worry is that when I was about 14 I noticed a pattern that if ever I was happy for a period of time, it would be followed by a similar period of time where I was equally sad. That isn't meant to sound negative, as I also knew that any time I was down it wouldn't be too long until I was happy again.
I found that these often lasted around 1-2 months, except as mentioned earlier, I have been happy for over two years now. There has been points, such as spliting up with Tara, that I thought that was the end of it, but alas things have constantly been getting better. I make sure not to take it for granted.
I just worry that all climbs have to come to an end... and the higher you're lifted, the further you fall.
So, in the words of Ronan Keating... "I am not trying to wash my hands of Boyzone. When people say I am, it makes it look like I'm trying to be this rock-and-roll star, which I'm not".
... Wouldn't it be ironic if I now die on a roller coaster.
