Metaphorically speaking, love becomes a mental illness.

Life is like a balance, which always needs some balance: one side is giving and the other side is receiving; On the one hand, it is to pay, and on the other hand, it is to get; On the one hand, it is cultivation, on the other hand, it is harvest; On the one hand, it is material, on the other hand, it is spiritual; One side is yourself, and the other side is others. God is embarrassed, too. He can't give you all the good things, nor can he put all the misfortunes on you. Only by looking down on gains and losses can we find the best balance point in life.
