colic!!!! HELP ASAP

Ok so my son is EXTREMELY colicky. It's going on 9 hours of nonstop screaming. Any suggestion you give about feeding, holding, car ride, change of clothes everything I've tried it. I've spent the last 9 hours trying to help him and nothing is working and he is refusing to sleep even went on an hour car ride to try and get him to sleep. I seriously need some advice on how to keep my sanity. This is an everyday thing sometimes 17 hours a day. I'm going insane and it's worsening my PPD. He's almost 3 months old and this has been everyday since he was born in to the point where I'd rather put him in day care for a few hours a day. I need advice or something I'm losing my fucking mind. I've tried rocking, car rides, laying down on the tummy, on the back, on each side, holding him, rocking him, walking around, stroller, toys, playing with him, trying to entertain him, pants and socks, no pants no sock, just in a diaper. Passy, cuddling, tv. NOTHING WORKS I NEED HELP PLEASE 
We use gas drops, special formula and he does go to the bathroom regularly. We see his pediatrician generally once a week trying to figure it out but we haven't been able to find anything that calms him.
