Travelling Europe in Aug! - Group Travel

I'm 19 years old from Singapore.

I'm currently working, but i've gotten 2 months off, and I'd like to find for travel companions to travel to Europe(UK, Netherlands, Ireland, France, Germany, Iceland, etc) in Aug-Sept, with.

Additional info: Would be great to attend Leeds/Reading Festival (23-25th Aug), Love TV shows/movies(Doctor Who/ Harry Potter/ Skins/ Sherlock/ Supernatural/ Breaking Bad, etc etc)

Attending a music festival during this period would be awesome too. Definitely have to be in August though, preferably after 10th. :)

Accommodation: Hostels/Couch-surf/Cheap B&Bs?
Dates flexible, but from Aug 10th on wards to Sept.

I love travelling, and would love to travel more! But my friends don't really travel as much as I would like to, thus, I'm looking to find more travelling buddies as, well, I don't really have any!
