switching from wordpress.com to .org, and my followers are gone

I had a webdesigner do a switch from wordpress.com to .org in order to self host and have my personalized site. i used to get more views and so many likes and comments on my posts and since switching i havent gotten any, and it seems my views have dropped. i understand there is no way to transfer the followers but i do have jetpack and am doing my best to use it. are there any tips on how to re popularize my blog now that its self hosted and i dont have wordpress.com? its very discouraging
