Why should you suffer in life?

I remember a few years ago I had nothing to worry about. I didn't have a great life, but a comfortable life. Yet, I always used to compare myself with others and dreamt of having a different life, if not a better life. There were times when I used to worry because I had nothing really to worry about. I felt like I wasn't living my life fully, hence I didn't have any worries. Do you know that feeling? You see everyone around me had something to worry about. Someone was going through break up, someone was struggling financially, someone's visa was rejected and someone lost their job. It's not whether they were successful or not. But, they had something to worry about. They are trying something in life. They had problems to solve everyday they wake up. Their lives were interesting. I used to feel like there should be something happening in life. And, there I was who was living a boring and dull life without trying to do anything. I wanted my life to be happening. I wanted to do something. I wanted to become something. I craved for that busy life, constantly juggling and constantly worrying. 

A few years later my wishes came true. I started to face problems. I had real worries to worry about. Surely, life became interesting but, honestly I didn't imagine that life would be so difficult with problems. I had all kinds of problems financial, emotional, physical and mental. However, nothing worried me as much as mental problems. I suffered hypochondria. The suffering was real. There were times when all I wanted was to be alive. To stay alive all day and to wake up the next day healthy. My imaginary problems manifested into real physical problems too. Like they say, thoughts are things.

At that time, I realised how smooth and comfortable my life used to be. But, I wasn't grateful for what I had. Only after experiencing suffering, I learned that one should be grateful for what they have. More importantly suffering makes you empathetic. Only those who go through mental problem can understand the pain of others who are going through mental problems, isn't it?

Suffering is inevitable in this uncertain life. I think one has to suffer in every way possible to appreciate life. Or, can one learn about suffering before they actually suffer and be grateful for what they have, and be empathetic toward others problems?
