been told i've pulled my hair out and hit my head on walls

Thank you for asking at Ehealth forum!

I read your question and I understand your concern.
This is not normal. These symptoms are consistent with acute psychosis. You would need psychiatric assesment for clarification.
I hope it helps. Stay in touch with your healthcare provider for further guidance as our answers are just for education and counselling purposes and cannot be an alternative to actual visit to a doctor.
Take care
