is this normal ?

My 7 month old baby is giving me the hardest time. He whines and cries all day to the point i don’t even want to be around him anymore. Ive tried everything and am doing my best to keep him happy, but it only works for 5 minutes and he’s back to whining and crying. I play with him, he’s fed and clean, i don’t know how to help him or what to do. I’m exhausted i work 5 days a week all day, and am up with him all day when i get home. i can’t take it anymore.
