Trauma doesn't always stay in the past. Even when you know you're safe now, your body and emotions may react as though something is still wrong. You might feel constantly on guard, become overwhelmed by certain situations, avoid things that remind you of what happened, or find yourself reacting in ways that don't always make sense to you.
For some people, trauma is connected to a single experience. For others, it developed through repeated experiences, difficult relationships, or circumstances that required you to adapt just to get through them.
Those responses may have helped you survive or protect yourself at one time. The problem is when they continue showing up long after the danger has passed.
Therapy can help you understand these responses, process experiences that continue to affect you, and begin feeling less controlled by what happened in the past.
