Are we there yet?

I am one of these unfortunate idiots in life that have an inane ability to over-think everything in the same way a scientist will try relentlessly to figure out the cure for cancer, or how the earth sort of 'happened' -the difference being that their thought patterns are wholly more acceptable and productive than my own. I can lie awake for hours letting my brain go at hundreds of miles an hour without even knowing the reason for my eyes popping out of my skull and the train of 'SHIIIIT', I'm just content being worried. And when I say content I mean I would happily swap brains with somebody else even if that included clawing the physical thing out of my skull myself.
My good friends laugh at what they call my inability to be happy, one said on the phone last night: "God, why are you so unhappy being happy? You don't need to moan about everything all the time you know! Just go with it!"
Well yes that's all very well for the rest of the world but I'm happy being unhappy with happiness in the small things because that means I don't have to think about the fact that - hey, I'm broke; I'm bored at university; I'm constantly exhausted; I'm considering buggering off to some forgotten land just to get my 'oomph' back.
Except, it's all very well to panic about how to cook a chicken, or where you're meant to be this evening, or does your tutor think you're hitting on him, but when I started panicking about my very happy relationship I was in desperate need of a severe kick up the arse (I was hoping there would be a chance it would go so far as to kick my brain into gear). 
But, to be fair to me, everything took a bit of a sudden turn recently into the 'serious' nature of life..and I hadn't particularly noticed, or had decided not to cotton on at the least, until it was a black-hole sized difference in the way he was talking rather than a bunch of little stars to admire at the time of passing on our little bubble of luuurve. But when the man turned round to me with a big grin on his face and said he had a huge urge to go riding on a tandem I started sweating instantaneously and I'm pretty sure the room was deprived of oxygen for a good few seconds before I said: "Tandem?! Are you nuts?!" Not only did it feel like I was being swallowed up by my future, I was being blinded by all the little cute things all at once - and let me tell you, there's a reason 'blind panic' holds such negative connotations. He didn't quite understand my reaction -luckily for him I couldn't figure out the nearest exit - but for me it was that image of us on a two person bicycle that made me realise just how far along we were in the couple time-scale. A tandem to me represents trust, dependency, sharing, equality - everything a (god-forbid) healthy relationship should be built upon. I just didn't know if I was ready to put it to the test. It felt so married couple-esque, so damned cute, so 'us'. For two people that had been flirting with the idea of a future together previously and had spent a lot of time together I'm not quite sure why it was this moment that it hit me, but there you go - I'm in the tandem stage of a relationship: we go shopping together, we're rational, we make plans, we think in terms of 'we' and we've already distinguished who the main breadwinner is (Oh come on, who do you think? I may be an idiot a lot of the time but I do know how to pick 'em!)
But after an hour long conversation at 2am last night - I woke him up and decided to panic directly at him for the first time - I've figured I really need to get a grip and enjoy it all. Supposedly happiness is good for the soul, which is a difficult thought for someone like me to entertain who was brought up to believe booze was good for the soul. I've since realised it is, in fact, the cure for the soul.
Anyway, a tandem also makes you think of summer love, being carefree, celebrating (or trying to recapture) youth and, most importantly, rolling around the hay - so I guess all is not lost.
