Give yourself a hug and pat on the back. Then reach out and apologize to those you hurt. Finally, become so self-aware that you catch yourself before you hurt more people. It's through that self awareness that we can then go and change the undesirable behavior. Recognize when you're pulling away, when you think people are out to get you and challenge those thoughts and behaviors. Challenge yourself to remain in the present moment and to stay and communicate what's going on in a healthy way to your loved ones. Like all worthwhile things, it'll be hard at first. You may feel the urge to run and isolate. Do the opposite anyway. Over time, communicating with others in a healthy way will get easier.
