Weighing a Decision

How do you go about making a tough decision? A serious decision...not like whether or not to spend that $100 on some splurge item or whether to say yes to an offer for a date? How do you actually go about weighing your options and coming to a conclusion you can feel good about forever?

For many months now, I've been faced with a decision, and I don't feel any closer to having a solid decision. And every time I try to do some research to help me make my decision, I seem to come up with the same question to consider: do you have a strong support system?

So, I don't know what's more upsetting...not knowing how to make this decision or not knowing if I have a support system.
