translate k-indie song lyric : Let's love myself(?) (coffee boy)

나를 사랑하자, 나를 사랑하자
Let's love myself, Let's love myself. (I think this means "Love me, Love me")
어제처럼 미련한 나를 사랑하자
Let's love myself who is stupid like in yesterday (Like yesterday, love me like stupid)
구석진 방 홀로 있는 나를 사랑하자
Let's love myself who be only in secluded room (I can't express this line in English)
나를 사랑하자
Let's love myself (Love me)


찬란한 미래를 꿈꾸며 캄캄한 오늘을 사는 나에게
to me who dream brilliant future and live dark today (While dreaming of a bright future, today you are living dark for me.)
아무것도 보이지 않아도 꼿꼿히 서 있는 나를 향한 노래
song for me who stand upright even if see nothing (I also can't explain this in English, but your translation is quite close)


거북이 느린 걸음으로 발버둥 치며 걷는 나에게
Towards me, struggling and walking amblingly like turtle
아무도 나를 보지 않아도 내 마음 지키는 나를 향한 노래
A song that's for me is always on my mind even though nobody looks at me


나를 사랑하자, 나를 사랑하자
Let's love myself, Let's love myself. (Love me, love me)
어제처럼 미련한 나를 사랑하자
Let's love myself who is stupid like in yesterday (Like yesterday, love me like stupid)
구석진 방 홀로 있는 나를 사랑하자
Let's love myself who be only in secluded room

나를 사랑하자, 나를 사랑하자
Let's love myself, Let's love myself. (Love me, love me)
여전히 아름다운 나를 사랑하자
Let's love myself who is still beautiful (Love me who is still beautiful)
눈물로 보석을 삼은 나를 사랑하자
Love me who makes tear to jewel
나를 사랑하자
Let's love myself (Love me)
