Baby Still Fussing

Its tiring for us that the whole night baby didnt have a proper sleep. She only sleep about 10mins and wake up from it, she drank milk like as if its hard for her to swallow at first (or like being force) but after few try its fine. Burping her its hard as she will stiften her whole body (when seating down). She prefer to be carry then puttin down to sleep. Seeing her like this pain me that she might be tired but coulr be somethinh bothering her (we suspect she got reflux or colic). We did everythinh but it doesnt help. LO just 1 month and we try everything in the internet . Its exhausting.
