8 week old constantly cries

So this is my 3rd baby. I thought I knew was I was doing. Wrong. This little love has non stop cries since 4 weeks old, and will not be put anywhere other than on my chest. I’ve been to the doctor who believed the cause of the crying was reflux, as he was throwing up all his milk after feeding, and straining/grunting in pain all day. They prescribed omeprazol and it’s doing nothing. The poor boy is never happy, I can’t recall a time where I was able to put him on his play mat, or a time where he has an alert awake period just looking around. No. Constantly crying. It’s exhausting for me and for him, and my other children are feeling the effects as I have little time for them. I have to babysling him in order to do the dishes, I have to carry him into the bathroom. And please don’t tell me to let him cry, because he goes PURPLE and sweaty and my heart can’t take it. I just need to know I’m not alone and it does get better. I just feel like it’s sucking the enjoyment out of the one thing I love the most, the baby stage. My husband is useless, works all day, will hold the baby and hand him back instantly when he starts crying. I have to shower with the baby, I eat with him on my lap, I pee with him in my arms, I avoid car journeys as he’ll cry the entire time, going for walks are a no go, he hates his pushchair and will scream until he’s in my arms. 😭😭😭
