막으려 해도 -> Even though (I) try to stop (myself)
날뛰는 내 모습 -> my looks on a rampage
* 날뛰는 -> raving, raging, on a rampage (adjective clause)
* 내 모습 - my looks
병적인 수위 -> a morbid level
초월했어 -> transcended
In fact, I would say 초월했어 is not a correct word here. It would be "넘어섰어" or "초과했어" which means "exceed".
Accordingly, the whole sentence could be translated into English as follows.
Even though I have tried to stop myself, the raving looks of myself exceeded a morbid level.
The English translation would sound awkward to native speakers but it cannot be helped if you try to translate one language into another word for word, not liberally.
