Feel like i'm having a breakdown 😐

My baby has colic and literally won't stop crying, he's on medication for it, which i've tried different types of and he's still crying all the bloody time, i'm close to breaking point. I'm crying and don't know what to do, i've left him in crib and tried to relax for a minute, i've went back to him and he's still crying and i'm getting stressed again. He doesn't give me a minutes rest and never sleeps, i don't know what to do, i'm freaking out here, i can't stand this crying anymore. And no i don't have postpartum depression, already been to doctors and i don't. I need advice i'm so stressed and tired!!! 😫
