Have A Deep Dent In The Skull. Medical History Of Epilepsy, Headaches. On Serequel. Several Ski Accidents. Treatment?

I have a fairly deep dent starting in the center and going all the way to the back of the skull. It's almost canyon like if u can picture that and everyone who feels it seems shocked. I am a 41 year old female with epilepsy (well controlled with deplore) and I have bipolar 2 disorder with many personality traits (impulsiveness, black and white thinking etc) associated with borderline personality disorder. I've had headaches in the past but don't now; however, I'm also on serequel which, amongst other psychotropics , makes me more relaxed. No stand out head injuries but several ski accident hitting head and neck (no loss of consciousness) and played soccer 12 years. Protruding discs both in cervical spine and lumbar. Intelligent, grad school and professional job but poor emotion regulation. In just giving you all the information I can think of so u can help me in assessing possible diagnosis and next steps. As an infant there may have been some neglect in care by my mother (I understand babies have a soft spot on head which should fuse). This has never been a big deal to me so never asked a doctor but realized if I were a guy with a shaved head it would be very noticeable to the naked eye and I've never seen this in anyone . Given this information can you provide me with possible diagnosis and respective prognosis. Many thanks.
