Requesting adoptees help

I’m trying to explain the shifting feelings that happen over the course of a lifetime about being adopted.  Would you share how your feelings shifted and became more complex with time (if they did)?  I think it’s important for parents to understand how feelings and your emotions can change over time re your adoption, how maturity, understanding of the larger society impacts those feelings good or bad.  I just want them to realize that feelings about being adopted, the impact it has on you is not something static, more that it is fluid and ever-changing.
