where can i find friends?

ive recently spilt up with my boyfriend who has also been my best friend for over two and a half years. he really has been my soulmate, i could talk to him about anything and i felt more comfortable with him than anyone else ive ever known in my life. we've decided to stay friends but i know we'll drift completely apart.
i now have no close friends at all. not that i really did before but now even less so, theyre all at uni while ive been on a gap year doing work experience. i havent got anyone to talk to about the break up for a start which is making me feel sad. and now i literally have one friend who i can spend time with so i should probably try and find some new friends but how? Im nearly 19 and theres nothing around where i live where i could meet people. im at a complete loss.
