My Pep talk every night!

I have a four week old that seems to be fussy all the time. (Maybe it's just me) but more fussy during 10-2am not all the way through those hours but I notice i can't seem to calm her down and she seems in pain if she has an episode lol. Every night I cry to my self trying to calm her down! I tell my self it's ok it's only like this for a little bit by 3 months it will get better and I'll get more sleep. Enjoy her now before you have to go back to work. I have to remind my self every night of this. I cringe at the thought of night time because I just want her to be "ok" not that she isn't but her "episodes" of crying seem as if I'm not doing something right. I've switched milks thinking it's her tummy and nothing. But the milk change has made her burp, pass gas, and pass stools more. If been told she's colic which I'm not sure because some days are awesome and some days are rough. I've been told it's witching hour? But never understood what that meant! I know my baby is still new to this world and it will all come together (I hope) but does it really getting better? Will she ever sleep more than an hour or two in the night? Will I ever not want to rush home before the evening just to "prepare" for the sleepless night? I am married but it seems like the male role in newborns is not dependable!! He waits till the baby is crying hard to get up and "ask" if I need help!! Like you couldn't just pick her up and take her for once? No I'm not going to ask you for shit when I'm already up! He rarely takes her without me having to ask him. For once I'd like to have him just "do it" I haven't been to happy with him since she's been born. He tells me I got her rest before the night time lol while I end up staying awake because it never works out. I can see my self getting depressed and I'm trying to control it between the sleepless nights taking care of the baby alone to the lack of i connection with my husband lately is becoming unmanageable ☹️ vent over
