Is my website hacked? So annoying! Please Help

So frustrating, first for the past couple months I was getting pop ups all over the place so bad that I couldn’t even log in at times. Then in the past couple days I have noticed when I log into my wordpress website to post updates, in the dashboard where I create a new post the screen is just blank white….nothing. Is my site hacked and how can I fix this problem?

Thanks so much ??
