Am I responsible for all of my problems?

Nope. What important is that you can solve this problems.
When you are happy with yourself, things will go smoother.
Soon, problem solved, and you won't have to worry a bit.
I am sure you'll do fine.

NO.most problems are caused by other people or the environment
you are born into.

Yes you are, everyone.

Of course not.

You are responsible for the ones that are bc of you.
