Crying non stop

My 11 month old won’t stop crying no matter what I do. I give him his toys. He stops awhile then start again. Turn on his favorite show that seems to help but again the crying continues. I change him, I play with him, I try to cuddle him... he fights the entire time pushes me away and tries to get on the floor.

He never was like this before... a sweet quiet lovable baby... now he seems to be satan spawn (figuratively). I don’t know what to do so far I’ve been really good at keeping my cool but I’m not sure how much longer I can hold on. Honestly, I’m surprised I’m not pulling out my own hair. It’s not separation anxiety because he doesn’t want me or his father he will literally swat at us like flies... I have no idea what’s going on with him. And his pediatrician won’t be back in office until September 2...

Any advice moms?
