"Head injury and concussion"

I had an accident at work with a wooden ladder falling from the ceiling, with no pulley system falling onto my head. I panicked that I was going to die I drove myself to the hospital. 

I was seen by a doctor straight away being a head injury and after an hour of cognitive behaviour testing the doctor said right you can go home now and I said no I don't think so - I am not okay and I am not feeling well and I have a high pain tolerance and there is something wrong with me. I explained I would be going home with no one to care for me and I felt I needed to be in the hospital in case I got worse. The doctor said no you will be fine to get in your car and drive home because you drove here and with no scans or brain imagery I was sent home. Even when I questioned the doctor about their thinking, I was told I would be fine to return to work the very next day with no time off and working a 9-10 hour day. Really?

A month after my injury, I ended up back at the hospital feeling like I am dying and was told that I am now at serious risk of having a massive stroke. I was also sacked the week after the injury at work because I became grumpy and felt really unwell while being forced to do a 9-10 hour day when I felt like I was going to end up dying. My work refused to pay my blood test and the doctor failed to diagnose a serious concussion.

I feel betrayed from the hospital doctors who treated me - who after a month then tell me I am at risk of having a stroke, but I don't feel they care enough to give me a CT scan or brain imagery.

I was talking with words coming out back to front. I stopped driving for a month and a half because I couldn't focus, I didn't smile for over three months and I kept walking into walls and doors and I slept for months on end. I believe my concussion lasted over nine months and I am still living with the effects today. I am struggling to cope with no help and an employer that has refused to pay workers compensation because they can't physically see a brain injury because the hospital gave me no paperwork. Really?

I am broken-hearted and I have lost faith in not only doctors but humanity!

I want to change the way that doctors here in Perth and Australia diagnose head trauma because I believe that they are not trained well enough in the treatment of a head injury. 

Why was I left to possibly die on my own, when I could have had a massive stroke, when I could have had a brain haemorrhage and I could be at risk of having a degenerative brain disease or cancer in the future? How is it that Sir Charles Gairdner Hospital doctors who treated me did not think it important to place me in a support group or find someone to help me, when I couldn't leave my home and being isolated, struggled to find anyone to assist me?

I should have been placed in a support group to learn how to live with a brain injury and what is going on inside my head and the fact blood was coming out of my ears the very next day.

Or to even receive a CT scan or brain imagery when all they kept telling me was they don't recommend them because I may receive brain cancer from having a scan.

Please explain.
