In remission, thinking about doing comedy again but i feel like i lost the music...

Before my cancer, I was enjoying life, finding joy and laughs in almost everything. I loved making fun of things and could see humor in nearly any situation. However, after battling cancer for over a year, nothing seems funny anymore. It's like I don't get humor now, and I can't stand pointless little things. I always loved comedy, and it used to boost my self-esteem. I want to fall back in love with the simple things again. My doctors believe it could be beneficial for me to try and find laughter in my suffering. Can anyone relate?

How can i start writting about little things...
