Hi there,

Yes, this is completely normal for a founder.
I won't repeat what has already been said in other answers but instead I'll answer from another angle.
Entrepreneurship is all about personal growth. If you want to be a successful entrepreneur, it requires an openness and willingness to grow personally even more than professionally. You have to deal with fears, overwhelm, lack of enthusiasm, disappointment, failure, and many other challenging feelings along the way.
I like to see this as an opportunity – the opportunity in adversity.
Since resilience, grit and self-care are vital skills for an entrepreneur to have, each challenge presents you with some valuable lessons to deal with them.
As for fear specifically, I love the brilliant story of going on a road trip with fear by Elizabeth Gilbert. A very effective and creative way to deal with the fear that will always show up when we try to do something new and exciting.
