IMHO, chicken doo doo.
However suggest you do a few practice runs on the weekend or day off.
Especially if you have a day off on a "normal" work day.
cycle to work, at usual time of day with what ever might become the normal things you would carry on your commute. Then stop at a coffee shop, get lunch, what ever - after that ride back home.
during these trial runs, often you can find slightly differed and more comfortable route choices that may make you more confident about commuting.
