Fussy Baby

FTM... I have a 6 week old who was born 3 weeks early.. I tried breast feeding but I just couldn’t mentally do it especially since I suffer from sever anxiety so I ended up formula feeding. I had her on pro advance and now gentle ease since she kept spitting up a lot. She somewhat spits up with this new formula but not as much. Anyways, the issue I’m having is she cries if she’s not sleeping or eating and all I wanna do is cry myself. Tell me I’m not the only one going through this and that there is light at the end of the tunnel.
