Your circumstances bring the words of American humourist Emra Bombeck to mind, “Worry is like a rocking chair: it gives you something to do, but it never gets you anywhere.” So, instead of rocking back and forth *and* repeating the negative thought patterns, take a break.
Focus on something you can control instead, something that reminds you that you are capable of doing things. Preparing yourself a warm, home-cooked meal is a good place to start. The confidence boost you derive from this will then help you take on the challenges head on.
Cosmic Tip: Change your focus.
