Colors seem darker in light"), but she's worried that counseling/psychoanalysis will oversimplify her problems ("Don't deconstruct and then fill me in/I'm not that basic, I swear/I've had enough of breakdowns and diagrams"). The verse about prehistoric bones is referring to traumatic events in her past--counseling would be like wiping the slate clean, but it would get rid of her history and in some ways herself.
