Won't sleep and low mood

Hi mum's please can you help me?

I have a 1 month-old son and during the day he will not settle I am breastfeeding and from time to time he will have a proper feed, then I burp him and he proceeds to cry and fuss and sucking his fingers but wont feed again for the next couple of hours until he wants another feed. I can't sit down without him crying and I don't know what to do it is making me feel very low and making me cry a lot aswell, I feel like I can't do it all day long just walking in circles crying my eyes out. 

Please help 😭😭😭
