There are ways you can express it in Korean, and if we say it in Korean with literal translation, it doesn't sound the same as you want to express your feeling. The first sentence of each line is when you talk to your friend and the second is formal or a respectful way of saying. 네 덕분에 오늘에 내가 되었어. (당신 덕분에 오늘에 제가 되었어요) 너로 인해 지금의 내가 되었어. (당신 덕분에 지금의 제가 되었어요) 오늘의(지금의) 나는 모두 네 덕분이야. (오늘의 나는 모두 당신 덕분이에요) 너의 도움이 없었으면, 오늘의 나도 없었을거야. (당신의 도움이 없었으면, 오늘의 저도 없었을 거예요) If you specifically refer to someone, you should replace the word "당신" with a proper one. for example, if the person is your teacher, you can say "선생님" instead of "당신". Also note that there are not many situations where we call someone as "당신" unless you are a little old married person and call your wife. ** If you have that kind of person you like to say it to, it would be awesome.~~
