When you think of trauma what do you think of?
You probably think it is this vaque complicated thing right, you think its PTSD, CTPSD, all this complicated stuff, and while that stuff can be related to trauma, let me tell you it is so much simpler than you think.
All it is, is unprocessed emotion that is the TLDR, no one has explained this well online or any were which upsets me.
As long as you can grasp that fact you will be good, and healing honestly is not that complex as you may think.
Legit just bring up an unprocessed emotion you want to heal, let yourself cry of you need to, or something like that and of you do not get that do a generic method like shaking, cold exposure, breath work and etc.
Simply make that a daily habit, repeat daily for all trauma incidents you want to heal and voila.
