Do you trust yourself?

Sometimes I feel like I don’t know what my own intentions are. And that they’re not as innocent and genuine as I make them out to be… I’m just not sure. I feel like I can’t trust that I’ll say what I want to say, or do what I want to do.
I have a hard time trusting my “gut” feeling, sometimes because I’m not sure what of two things it’s saying, sometimes because I’m not sure it’s saying the right thing to do…
Is this competely normal? Do you trust yourself? Do you feel like you’re in total control of what you want, and what you do? Do you feel like what you want and what you do is “correct”? How do you get to feel that way?
How do you feel comfortable enough, have enough trust with yourself, to “let go” and do what feels right?
