Just going through it

Man am I struggling. I feel like running away. FTM to a beautiful 5 month old baby boy. He’s amazing but he is so tough. He was born screaming and hasn’t stopped. He was VERY colicky for first 4 months and now is starting to come out of that fog. But he hit his 4 month sleep regression around 3 months and if it’s not all day screaming from colic, it’s waking up and screaming for 2-4 hours straight a night. He naps for 10-30 mins. I’ve read every book. I do everything they say, black out blinds, appropriate wake windows, sound machine, etc. I took the taking cara babies newborn class and am currently on night 11 of her ABCs of Sleep and he’s still not sleeping. He has no health issues, the doctor says he’s perfect. He’s just so tough. I haven’t slept a full night since I was 7 months pregnant, which may not be so bad if he weren’t colicky and now constantly overtired. Anything he goes through it’s to the max intensity wise. I feel like a complete failure. We’re the last in our family and friends group to have a baby and no one else has dealt with what we are dealing with. I feel like they all think we’re just being dramatic. I just needed to sit down and type this up.
