Is it normal that I lost interest in everything?

In my early 20s, I had lots of dreams. I was eating healthy, working out, always learning and improving, wanting to go to best places, having lots of money.

But now at the age of 34, everything started to seem pointless to me. Did i become a very mature man, or do I feel like this because too many bad things happened in my life and the world for the last 6 years.
