Congrats, welcome and I feel for you. First, keep saying this in your head, "this too shall pass." Say it again

Just kidding (sort of) Hopefully the worst will be over in a few weeks. We thought the book, "Happiest baby on the Block" was an absolute lifesaver. We STILL use some of the techniques with our 5 month old.
-Swaddling, tight. She still likes to be wrapped up for early sleep and naps
-She almost always will stop crying if we use this...sit on the couch/chair. Place on her side in you lap, head by your knees. Rock your legs back and forth pretty vigorously, while supporting the back of her head. (It's supposed to re-create the womb)
-The book talks specifically about colic issues
Good luck...it will be better soon
