It is literally impossible for any thought to be otherwise than infinite; a thinker cannot be otherwise.
You are entirely negating Kierkegaard's point. If it were literally impossible for a thought to be finite as opposed to infinite, in the way he is using the term, then no one would "lose his mind," if it's the very finitude of a thought which makes it maddening to cling to.
So either you are negating his point or missing it. Your classifying all thoughts as infinite is based on thought itself being intangible. You do not have to "find" a thought's temporal beginning or end to be sure it has both things. Thoughts can and do recur, which implies temporal limits. And you obviously do not think all thoughts at once, at least not on a normal basis. Also, you imply a thought has no boundaries in meaning. That is plainly a self-contradiction, unless there was only one possible thought.
To address Loki's question, I think Kierkegaard was speaking about the resiliency of a thought, when a notion assumes the mantle of dogged conviction. If one clings to it, one will either sink or swim, depending on whether it is infinite or not. If it is finite and one clings to it, one cannot adapt and a rift develops between what one does and what the circumstances call for. The tighter one clings, the deeper the rift in one's psyche, and the more pronounced the outward manifestations. "Losing one's mind" is just a way of describing this schism, the schism from which a schizoid person suffers.
But if it is "infinite," then a thought becomes the truth and clinging to it would keep one from perishing or else being "ground into conformity," which can appear to be quite the same thing.
