I think this means. . . Love is like a cold, but it is a bad cold. It may cause dizziness, fever, stuffy nose and runny nose, which means he may cry often? Still think I still miss you? When people are sick and drunk, it is easy to think of the past or hallucinate. On the other hand, I think he may think that love is like a bad cold, which makes you feel uncomfortable, but you just need to recover slowly or take medicine to recover. A cold is common, but it can't be said that love is common. So a heavy word is added, which means that everyone will catch a bad cold, but it is rare but normal. I can only explain these. Anyway, I wish your "bad cold" a speedy recovery ~
