You’re afraid to get hurt. It’s not abnormal. Nothing is abnormal. Depression is normal, too.

Emotional pain makes you withdraw from life, and from other people. There’s nothing wrong with it.

You need to learn to process your emotional pain, not by running away from it, but by allowing it to be. Don’t feel like you have to do something about it (like ending a relationship). You don’t. Make a clear disinction between your actions and the pain itself.

Next time someone does something painful for you, distance yourself and allow yourself to hate them. Don’t engage. Spend some time alone if you have to. Don’t suppress any hatred you feel towards them, but don’t express it to them either. Just allow it to be. Cry, scream, punch the pillow if you have to. But don’t talk back, don’t act in revenge, don’t try to fix them or fix the situation - this will only feed into the cycle. Just process it.

When you allow yourself to feel whatever it is you feeling, it eventually will release you.

You can’t get rid of emotional pain. There will be pain. Such is life. You can only become friends with it, and not let it make you do silly things. The less you try to run away from it, the less power it will have upon you and your actions.
