Going bankrupt, or is there another option?

When i turned 18 i went silly with phone contracts and pay day loans, im now 19 and a half, and have 5000 in debt to Company and 3000 to family and friends, it wrecking my life and i don't know what to do any more, i get paid every month and all my money just goes straight out to company's automatically, i did try to do a debt management course but it did not work as my money would also go else where every single month, i don't know what to do any more, is bankruptcy a option, i just don't know what to do, or get a big loan to pay it all off and just pay 1 company back every month, any advice please?
