What's the meaning of the sentence? ​​I feel decidedly morbid.

Start to read The little prince again I read it about one and half years ago. Before that, I had heard about the book. It seems everyone loves it. In fact, so do I. The book of little prince reminds me of the story ——the happy prince which is written by Oscar Wilde. I read it when I was about ten years ago. I really loved it. When I read it again in my second year at college, the feeling is gone. When I graduated, I read the English version, still had no feeling. Now, I start to read the little prince. I don't know whether it gives me the feeling...

explain the first sentence, please! You're way too good for this（Don't be sad）. If he isn't the one. There's going to be someone else who will appreciate you, son. I will support you. I don't understand the first sentence...can you explain it detailedly. especially, What's the meaning of “way” in first sentence?

I really love you I'm sorry for my bad behavior this morning. I just cannot control myself. I thought it would be a good day. The nice weather（I like raining days）, and the fresh air really made me happy. However, It must be a bad day for you. Because I did these silly things. When I sat down, I cannot concentrate at all. Now, It, too, was a bad day for me.
