Thank you for your replies they've been quite helpful, in response too the couple of questions:
How long have I been aware of this? Er, well I've kinda had them for years but I only started kinda really noticing and thinking over them about two years ago.
Have I been diagnosed/Am I on treatment? No. I'm kinda a bit over cautious about talking to my mum or doctor about them because I'm not very up on talking to people I know and such and also whenever I plan to talk to mum about it I manage to convince myself out of it and that I'm just being silly.
