Everybody gets little stressed when they have to make a big decision (yes, even you, Sag!), but there are ways to make the process easier.
If the stakes are high and you have two choices (we're not talking blue or green shirt here), take the time to ask yourself if there are really only two options.
Perhaps you're thinking about ending a relationship (maybe your S.O. told you what to do one too many times!) Are the only options really to break up or stay together?
Is it an all-or-nothing deal? Consider taking a break from each other for, say, two weeks. That sounds a lot less harsh than "I'm outta here!"
