How to deal with adulthood and overcoming trauma with no help?

Hi guys!

Had a bad upbringing that led me to being depressed, anxious and isolated. Have tried multiple psychiatrists and psychologists but they seem to not understand the root cause despite mentioning it to them. Multiple therapists have abandoned me and some sessions have left me questioning the validity of my trauma and feelings. This is affecting me a lot and i am not sure who to reach out to. I am so lost and in desperate need to find direction but I am unable to.

Any suggestions or coping mechanisms would be appreciated!
