All is to be feared where all is to be lost.

Fear grows in proportion to exposure. When everything you have rides on one job, one person, one deal, every small tremor becomes a genuine threat, and your nerves are reading the situation correctly rather than failing you. The anxiety is not a flaw, it is a report on how much sits in one place.

Rather than arguing yourself out of the worry, reduce what it is measuring. Build the second source of income, the second friendship, the saved month of expenses. Spreading the stakes is slow work, and it quiets a kind of fear that reassurance never touches.
