No money? Why not start a fundraiser to help you get funds to get well? Here's the one that my friends started for me: https://www.giveforward.com/fundraiser/ckx1/elizabethspromise
It's pretty easy to put together, then you can share it with your Facebook friends.
Once you've raised a little money, I would order a saliva panel from somewhere like Direct Labs, although you may need to find a lab like this in Europe, not sure. This is the panel that I would order from Direct Labs: https://www.directlabs.com/mobile/TestDetail.aspx?testid=499
I would also buy this book to share with your parents: http://www.amazon.com/dp/1890572152
I'm seeing a copy as cheep as $3.15. I bet you can afford that.
Okay, that's a start... Bring us your saliva results and we can walk you through the basics. The book does a pretty good job, as well.
