I was once taught (based on a psychologist named Ellis) that two different people can go through the same trauma, and it affects them differently. One example given was that two girls are abused and one can't get over it, so can't get a job, or a relationship, and ends up alone and miserable, whereas the other girl trains in a job to help abused girls get counselling, fundraises for charity, gets married and has kids, works at a soup kitchen every Christmas ... You get the picture.
The difference, it seemed, was whether each person entertains certain thoughts in response to what happens to them. Apparently, if you hold onto thoughts of; "I can't" or "it shouldn't" or "it ought" (to be different), then you will not come out of it too well.
Another example given was two people at a train station. The announcement is made that the train will be late, and one person thinks "oh that's not what I wanted, but I will grab a coffee and a paper and make the most of a bit of time to chill". The other person panics "oh no! I will be late! I CAN'T be late! I really OUGHT to be on time! The train SHOULD be here at the right time!
Who is going to come out best here? So the way you VIEW what happens to you makes a huge difference in your survival. And you can change how you view things.
A person can be late for work. A train can be late. If you think of the "cant's" "oughts" and "shoulds", you won't settle back and read the paper with a coffee as you wait for the train.
The same thing happens to both people but one gets out of it a mangled ball of stress for the rest of the day, and the other a chilled, relaxed person who was a bit late for work through no fault of their own, forgets the inconvenience before lunchtime.
They both have a choice with how they learn to view it.
So do you.
It doesn't stop abuse happening, and it doesn't belittle the trauma people to through, but it does help to move on and get through things that you may think SHOULD have been different.
Can I suggest you self refer (or ask a gp to refer you) for cbt? That may help you learn good coping strategies for survival.
I really wish you all the best
