That really sums it up. Yeah, we all go through the 'clown makeup' phase (unless you're perfect or have someone sympathetic to assist you. Yay you)
But we all have to start somewhere. The only thing I can add is to start small. You will have a 'comfort zone.' Push it a little bit. Then a little more.
Just don't get overwhelmed. That's a surefire way to make yourself feel bad about yourself.
