So fucking sleep deprived 😩

My son is 3 months, he has colic, screams all day, goes to bed around 8-9pm and then wakes up at 12am for a feed and then he's awake for 4-5am and doesn't go back to sleep, I'm at my wits end with these 4am starts to my day, he just cries all the bloody time, my head is sore constantly and I'm exhausted, what the hell am I meant to do, he's been on every type of medication for colic, I do bicycle legs, massage his tummy, I burp him, I do everything that has been advised and he's still a nightmare, his no sleeping and screaming are making me so fucking ill😑
