Screaming bloody murder at night?

Anyone else? My LO is 16 weeks & lately when we put him to bed he screams, shrieks, cries and goes absolutely psychotic crazy until he is dripping sweat. No amount of rocking shushing singing hugging is working. Please someone we are at the end of our ropes. It has gotten so bad that we have to just walk out & leave the room. I hate letting him cry but omg its just the most intense situation ive ever been in!!! I have so much patience normally but this is the first ive ever felt myself actually losing my mind. He is fed, changed, swaddled, has white noise, & ive tried warmer and cooler clothes. Ive also cut out dairy completely. NOTHING is working. My daughter was never like this so i am having a really hard time adjusting to this intense behavior. I guess just looking for comfort and advice. Thanks for anyone who is listening and willing to share.
