How can I stop feeling lonely?

I'm 16 and i've never have a boyfriend. I just haven't found anyone I really like yet, and it's summer now and almost everyone I know is in a relationship. Everywhere I look there is couples holding hands and kissing and it's really making me feel down. I don't have that much money right now, and I can't get a job because i'm going away this summer for 3 weeks. But I am just feeling really lonely and I need something to occupy myself with. I only have like 4 close friends who I hangout with, and two of them are in a fight so we can't all hangout together, and my other friends are gone away for this summer so basically I don't have anyone to hangout with for 2 weeks.
