Books to help me become a better person.

As the title says, I want to learn to become a better
person. Rediscover kindness and thoughtfulness.
selflessness and tenderness

I've been through 7 years of personal tragedies and
to be honest, mentally, it's really taken it's toll. I've
realised in the last year that, I'm simply not the same
person anymore. I feel like I've lost part of my core,
bit all the parts that made me who I was. I've got 3
young kids and I'm 34. I really don't want to be stuck
this way and I want to be a role model to my kids,
with as much positivity as possible.

I should probably be seeking therapy rather than
book suggestions. But here I am.

Even one suggestion would be really appreciated.
Thank you for reading.
