💐🍫 anxiety is horrible, really horrible.
Are you generally getting any sleep? Are you eating and drinking?
What support do you have?
Please, do NOT put bumpers in his cot. If he wiggles up & bangs his head, he's not going to do himself any harm, none. Bumpers on the other hand, can kill. Any kind. Really, don't use them or anything else inside his cot. Definitely not a pillow or anything. A small tap to his head which he will barely feel is far preferable to the dangers of soft things in babies beds.
Silver lining...he's given you a warning about how mobile he is, so you'll need to watch putting him on your bed or a changing table.
My Mum kept a small mirror beside my cot so if she couldn't see me/hear me breathing she could check without waking me. 😊 No one needs to do that now, I developed a fog horn warning system! 😂
He's tiny, he's new, he's your first - you'll get through this.
I hope you have someone to look after you both today & allow you to get some sleep. Sleep, food & lots of water etc - it'll help.
See your GP when you can.
