Anxiety

Is anyone one else suffering from post partum. I'm a mess at about four to 8 in the afternoon. It's like the whole night time routine scares me. I have a toddler too and most days go pretty good but some days my baby just wont go to sleep. At 5 weeks old it's like as soon as you lay him flat he's like ooh I have to get mommy's attention. Or something goes wrong. Any ideas as to what to do. I thought maybe acid reflux but the meds aren't working. Today's day three of that and they make him super gassy. So now he suffers with that. Please I need some either mental health advice or kid advice. And please keep the rude comments to your self I'm having a hard enough time with this as it is. Never had this with my first. Thanks.
