Help needed

I’m really in need of some advice as I am at breaking point here.

My little boy is 5 weeks old and just point blank refuses to be put down day or night. Whether this is to sleep or just for 5 minutes whilst I pop to the toilet, make myself a drink etc.

I’ve tried everything. We have a carrier, car seat, pram, swing, bouncer, crib, moses basket & snuzpod and he refuses to be put into any of them. He doesn’t sleep at night unless I am holding him so I have to stay awake all night with him on my chest, terrified that I am going to fall asleep and roll on him. As soon as I put him down he screams to the point where he wheezes and I worry that he is going to harm himself.

I’ve tried swaddling, elevating his crib, I will stay up for hours trying to settle him and he won’t even close his eyes.

I’m on my own 24/7, I have no family or friends that can help and I haven’t slept for 5 weeks, this doesn’t look like it will change any time soon. My GP and health visitor won’t help me and I am feeling so tired, lonely and depressed.
