am I the only one?

I'm a FTM and I feel like I've been having such a hard time adjusting to motherhood these whole 5 months..since the beginning it's been one thing after another.. my LO is very needy and he's had silent reflux, colic, constipation, colds, cough, multiple hospital visits, and has never been a good sleeper.. I feel like every month I hope it'll get easier or better..as I read other moms talking about how they have an "easy" baby or a "quiet" baby or a "mellow" baby. Mine is always fussing.. even when he's fed, changed, being entertained etc..he'll start whining.. Ive been sleep deprived, sometimes don't eat well, been sick at the same time he is, and my period is heavier than before I was pregnant so I bleed a lot..I know I'm complaining but I just really want a month or couple of weeks where things are at least a little easier with him.. where he's happy for longer periods of time.. playful.. doesn't need to be constantly carried.. I just feel like I'm going a little bit crazy. 😩😩😩😩
