CT Scan - Terrified I’ve damaged my body with radiation

hey,

I’m a 22 yo female who has suffered with severe health anxiety from the age of 14/15.

During my worst periods, I would force my parents to take me to A&E countless times because I was convinced I was dying.

Things have improved, but the last few days I have been feeling more and more anxious about the fact I have received TWO CT scans of my head at such a young age for practically no medical reason other than my anxiety.

Whilst I know I have no one to blame but myself, I am frustrated that no one (Drs or parents) simply refused the scan on the grounds of me not being in a stable mental state and in fact being very severely mentally ill.

I now feel as though I have given myself a life sentence because of a stupid decision I made when i was so young and mentally unwell.

Is it likely I am now going to get brain cancer? Any advice much appreciated.
