PTSD

PTSD (Post-Traumatic Stress Disorder) is what happens when your brain and body don’t fully “come back” from something overwhelming, scary, or deeply distressing. It’s not just remembering something bad. It’s your system still acting like it’s happening right now, even when it’s not.

What it is
PTSD can come from any experience where you felt:

  • Unsafe

  • Powerless

  • Overwhelmed

  • Or like something important (your safety, identity, or sense of control) was threatened

That could be:

  • Abuse (emotional, physical, sexual)

  • Violence or accidents

  • Loss or sudden trauma

  • Medical trauma

  • Chronic stress over time (not just one big event)

Important: it’s not just what happened. It’s how your nervous system experienced it. Two people can go through the same thing and process it completely differently.


What causes it
Think of depression as the result of multiple inputs stacking up:

  • Biology: Brain chemistry, genetics, sleep disruption

  • Psychology: Thought patterns like self-criticism, perfectionism, or hopelessness

  • Life experience: Stress, loss, trauma, burnout, major transitions

  • Environment: Isolation, lack of support, or feeling stuck in your circumstances

It’s rarely one clean cause. It’s usually a slow build.


How it shows up
1. Re-experiencing

  • Intrusive thoughts or memories

  • Nightmares

  • Emotional flashbacks (you feel the same fear or shame, even without a clear image)


2. Avoidance

  • Staying away from people, places, or conversations

  • Numbing out (emotionally flat, disconnected)

  • Keeping busy so you don’t have to feel


3. Hypervigilance

  • Always on edge

  • Easily startled

  • Overthinking, scanning for danger

  • Difficulty relaxing, even in safe situations


4. Negative shifts in thinking and mood

  • “Something’s wrong with me”

  • Guilt, shame, or blame

  • Feeling disconnected from yourself or others

  • Losing interest in things you used to care about


How it impacts your relationship with yourself
This is where it gets heavy.

PTSD often rewrites the way you see yourself:

  • You might feel broken, even if you logically know you’re not

  • You may not trust your own reactions or emotions

  • You can feel out of control internally, so you try to over-control externally

  • You may disconnect from your body just to get through the day

It creates this gap between who you are and how you feel inside.


How it impacts relationships with others
PTSD is relational, even if the trauma wasn’t.

It can look like:

  • Pulling away or isolating, even from people you care about

  • Struggling to trust or open up

  • Overreacting in moments that feel small to others (but aren’t to your nervous system)

  • Feeling misunderstood or “too much”

  • Or the opposite, shutting down and becoming hard to reach

You might want connection, but your system reads closeness as risk. That push-pull can be exhausting, for you and for the people around you.


The simple takeaway
PTSD is not just about the past. It’s about how the past is still living in your present.

It’s your mind and body trying to protect you, just using outdated information.

And the key thing to understand:
What you’re experiencing makes sense based on what you’ve been through, even if it’s not helping you anymore.
