I have trouble feeling heard

My biggest flaw is trying to express a concern or feelings that are not being acknowledged or dismissed and so I keep on digging the subject. Sort of being a dog with a bone. I am aware this has something to do with my upbringing since there was no emotional validation and gaslighted. My husband sometimes trigger’s this but never told him why exactly aside that I was bullied a lot in high school. I don’t think he would care and I don’t want him to see how dysfunctional my relationship with my family was.

When, I’m in conflict with my toddlers, I see the triggers and literally think not to act like my parents. I’m definitely breaking the cycle but somehow I’m sort of healing myself in the process! It consumes my mind how I’m still desperately seeking my parents validation that I’m good enough. Is this normal?

I can’t afford therapy right now but is there another way to accept what was and let go so it won’t affect my life?
