I stopped getting likes on facebook. What should I do?

Like on my last profilepic I got 150likes easily and it added to 198 in a month or something. Now I changed it and it got only 108 in 4days. So I tought maybe because it wasn't pretty enough. But now i changed it again and I got only 10in 10mins. Normally i would get 50in the first 10mins... what is happaning? Uis it bc summer holydays just started and nobody is on fb that much or does everybody suddenly hate me? HELP!!!

I wanted to say something about all these mean comments this question got: No, fb is not all what matters, grades and stuff matter more I don't know how it is in other countries but in Belgium the likes and followers on FB are REALLY IMPORTANT. If you don't have at least 100likes that means nobody cares about you. Likes and followers are really a big deal here so I'm worried of becoming an outcast because from 170likes you are seen as populair. Less than 100 is fatality for social life...
