And, 진료를 받으러 싶어요 -> 진료를 받으러 가고싶어요

And 주일 is same as 개월 일주일 이주일 삼주일 사주일... 주 can be used both words. 일주 이주 삼주 사주... 한주 두주 세주 네주....

When you say -달, you should say the number differently. 1 month : 한달 (ㅏ is omited from 하나 and ㄴ would be the final consonant of 하) 2 month : 두달 (ㄹ is omited from 둘) 3 month: 세달 (셋 - ㅅ) 4 month : 네달( 넷-ㅅ) and다섯달 여섯달 일곱달 여덟달 아홉달 열달. 열한달 열두달 열세달 열네달 열다섯달... But 개월 is 일개월 이개월 삼개월 사개월 오개월 육개월 칠개월 팔개월 구개월 십개월... it used the number as it is.

걸어가다 and 걸어오다 is also same. 걷다 is the origin word of 'walk'. 걸어오다 means that a person walk and go to where you are now. 걸어가다 means that a person walk and go another place that is far from where you are.

오다 and 가다 has difference by your position standards. 오다 is used when a person move to where you are. Also, it can be used when you or other person who are in same place(this is can be you) go out and come back the place. And 가다 is used when a person (or you)move to the place far from where you are in now. So it can be used when you move to another place. So, saying again, moving to where you are or moving from where you are. So 데리고오다 is used when someone picked up other person and go to where you are. On the contrary, 데리고가다 is used when you or someone picked up others and go to other place. 데려가다 and 데려오다 is shorten words of aboves.

It's a big adventure to believe someone. It was already water spilled and it's all my fault that I didn't even check properly by the reason of friends. My relationship is spoiled again. If he/she cannot get along with me and is not my relation, it can't be helped. (I translate it little indirectly.)

It is complicate explaining it... As another asker said, this means 'the year of blue horse'. I explain the meaning of 청마해. In Korea, people used special year cycle every 60 years. This is combined 10간 and 12지. 10간 is 갑, 을, 병, 정, 무, 기, 경, 신, 임, 계. Especially, 12지 means each animals, 자(rat), 축(cattle), 인(tiger), 묘(rabbit), 진(dragon), 사(snake), 오(horse), 미(sheep), 신(monkey), 유(chicken), 술(dog), 해(pig). And combining 간 and 지 one by one in regular sequence. For example, 갑자년(갑 + 자 year), 을축, 병인, 정묘, 무진, 기사, 경오... So 2014 is the years of 갑오년. '오' is the horse, so this is the year of the horse. And... second. Why is the blue? From the ancient, 10간 have some meaning of each colors. 갑and 을 mean blue, 병 and 정 mean red. 무 and 기 mean yellow, 경 and 신 mean white. And 임 and 계 mean black. So 2014 is 갑오년, as I said. 갑 means blue. So, 갑오년 is the year of blue horse.
