A tool that you could use from SMART is a cost/benefit analysis. Here is a link to the CBA worksheet.

The objective of a CBA is to help you take a rational look at the decision you are contemplating (the pluses and minuses of each side of the situation) and hopefully help you to determine what would be the most rewarding/advantageous path for you to take. Once you are able to feel confident about what would be the best decision for you to make that should alleviate some of the stress you are feeling.
