Take a deep breath, sit down and make an emergency plan. Decide what emergency you are preparing for and what supplies you will need. Try and stay within a certain emergency time frame and work your way up to larger scale emergencies. For example, begin planning for a 72 hour emergency and work your way up to a short term emergency and later, a larger scale or long term emergency.
Take your time and properly plan how you are going to open up your budget so that you can attain these emergency items. Cutting out the extraneous spending in your budget can free up a lot of extra cash. The money saved can be used toward your future preparedness items. Make the choice of using the new found preparedness money or save it for a more expensive prep. Either way, you will accumulate a little at a time and not break the budget.
