Thanks all so much for your comments.
I got my concussions in all freak incidents - the first I was hit by a motorbike, the second someone fell on me and we both fell into a wall where I hit my head and then the last one was from me feeling dizzy and I fell over.

Yes I am taking amitriptyline. The doctor said 2 months was enough time for it to make me feel better. I ran out of tablets so it was a cold turkey situation. I emailed her asking her for advice and she said I would have to go and see a specialist in China which is irritating because I don't really trust them here thanks to bad experiences.

I will have to go back and see someone anyway because I can't carry on like this. It's got considerably worse. I came off them two weeks ago and the first couple of days were okay because I was on holiday and relaxing but now i'm back at work etc I feel like i'm back at square one.
