I can't speak to everyone's experience or abilities, but I can say that one of the hardest things about overcoming abuse is identifying what reality is and distinguishing the difference between what is true about who/what you are and something you are gping through as a result of the experiences you had.
Between the inflexible authoritarian way my parents were, and the coping mechanisms I used to make it through the years I lived with them, it was a many-years-long journey later on in my adult life (and still ongoing) to work back through the layers and shift the foundations from where they were involuntarily built to where I wanted them to be.
I have a particular grief, for the time in my life I could have been more like who I may have been had it not been for abuse and trauma. The years of lost experiences and mistakes that may have been much less arduous had it not been for the coping mechanisms I adopted for survival. When you say you don't know how to complain- I think it may be more accurate that you may have trouble with communicating with/relating to other people, or you can't find the proper way to articulate how big of an impact or determine at what point something is really part of you or a mindspace you find yourself in.
I spent a long time trying to deal with it on my own, but where I really started to make traction was talking to a professional and actually being honest, painfully so when it came to my dysfunctional way of dealing with intimacy. After some years I was able to begin admitting where I was the source of my own anguish and forgiving myself but also taking accountability of putting in the work to change what I could so I could live life more functionally and really be able to experience things without that weight I hadn't realized I had been carrying all along. To an extent I had become attached to it and it became an extension of me, a part of my identity.
My family in general was (in some ways still is) incredibly problematic, and I've come to realize a lot of the problems started with a desire to be validated and/or accepted by the parental figures. Not saying this is the case for everyone, but it is possible to forgive people (and still love them, if you wish) who caused a lot of harm, and work to heal. You deserved better, and future you can find what you yearn- it's not an easy road working through all that but there is hope to be found in the process which may not have felt feasible otherwise.
