Find experienced people to talk to. People who have been through what you’re going through can help you understand what feelings are normal and expected (as well as how to effectively cope with them). In my case, having people who have gone through similiar things on call has helped me stay on an even keel when emotions run high.
Stay objective. Friends and family often are too invested in how your decision changes things for them to be objective about what is “right.” Talking to people who don’t have a direct interest in your results ususally can be objective. Really helps.
Avoid hostile people. If people around you are reacting via passive-aggressive behavior or all out rage, bullying you or actively retaliating against you, do not engage. This can be incredibly tough when people you care about are trying to sabotage your attempt to live a good life, but you have to hold strong. Make it clear you’re not going to react to provocation.
Crying is good sometimes. You won’t be strong every day. Some nights you’ll cry for an hour into your pillow. Sometimes the stress of people you care about reacting so harshly against you will hit you like a crashing wave. Sometimes you’ll miss the old way of living, even though you know the change you made was for the best. This is natural. Don’t fight the wave, but give yourself a chance to let it crash over you and dissipate.
Remember your body is a temple. The stress of a major decision in combination of fallout from others can shake to your core if you don’t take care of yourself. Get a good night’s sleep, no matter what. Get exercise. The long walks and physical exercise I’ve been getting over the last year have been critical in helping me keep things together. Watch what you put in to your body. Listen to your bodies reaction to certain foods. Which ones make you sleepy? Which ones make you jittery? What foods make you feel good and healthy and strong?!
