There are a lot of variables here - are you an adult or a minor? Do you live with your parents or on your own? Etc.

One thing you could do is work with your own therapist to be able to come up with something concrete to tell your parents that would help you. OR invite them to a therapy appointment where you discuss concrete ideas.
I don't really think it is just up to the parents to figure it out on their own even if you are a teenager - you have some idea of something - just sitting and telling them that your parents are stupid is not going to help either of you. Plus, without your input, what they come up with and what you want could be different things.
