People often tend to say "it wasn't as bad as X...", and the thing is, you could have been physically abused or sexually abused as a child for many years, and likely you would still have said "other people have it worse, I at least wasn't starving", for example.

What matters most for you is the impact of your lived experiences (whether it's trauma or not) on you, so that perhaps working through them can help ease the chronic symptoms.

You don't have to use the word "trauma" if you don't feel it fits.
