I wanna add that the term "trauma" in the title is a bit misleading if you're asking for "terrible childhood" / bad upbringing, etc.
"Trauma" is a very restrictive term usually only reserved for experiences that were life threatening.
Trauma is when we experience very stressful, frightening or distressing events that are difficult to cope with or out of our control. It could be one incident, or an ongoing event that happens over a long period of time.
Most of us will experience an event in our lives that could be considered traumatic. But we won't all be affected the same way. Trauma can happen at any age. And it can affect us at any time, including a long time after the event has happened
Childhood trauma
You may have experienced trauma during your childhood. These experiences could make you more likely to have mental health problems as an adult. This is especially if you didn't have support to manage the trauma. Or if you experienced trauma continuously, over a long period of time.
"My high functioning depression and anxiety is a result of childhood trauma that lay dormant from age 13 until it was triggered when I was 39."
There's no rule about what experiences can be traumatic. It's more about how you react to them.
What's traumatic is personal. Other people can't know how you feel about your own experiences or if they're traumatic for you. You might have similar experiences to someone else, but be affected differently or for longer.
Trauma can include events where you feel:
- Frightened
- Under threat
- Humiliated
- Rejected
- Abandoned
- Invalidated, for example your feelings or views have been dismissed or denied
- Unsafe
- Unsupported
- Trapped
- Ashamed
- Powerless
Ways trauma can happen include:
- One-off or ongoing events
- Being directly harmed or neglected
- Witnessing harm to someone else
- Living in a traumatic atmosphere
- Being affected by trauma in a family or community, including trauma that has happened before you were born
