FTM question

Being a mom is hard. I have a 5 month old and the real fun hasn’t even begun yet! This is my first baby, and honestly he has such a great personality already. This isn’t really about him though, it’s about me.

I miss my baby when he isn’t physically with me. Like right now he’s laying in his crib sleeping, and I wish he was in bed cuddled up with me. I’m not going to move him or wake him he sleeps so good in his crib and we’re trying to get on this routine where he falls asleep all cuddled with me, then I wait a bit, move to his crib. And I mean, when he is in bed with me, I want to be free and do what I want, but I miss my baby so much! Ugh. I have been struggling with this a while now. A couple months ago I got a job, however it involved leaving him for hours and like I’m not sure if I’ll ever be ready to leave him anytime soon. Idk what to do. I leave the house at times to go shopping or whatever and he stays home with grammie but like I know he’s safe, I know where he is and basically what he’s doing. Basically in a nutshell I don’t want to be far away from him for very long. Feels like separation anxiety, never had it before but like what do I do? Does this ever get easier? From one mom to another did you go thru this? What helped you? Please share some insight, I don’t wanna be one of them moms who struggle to let the boy spend the night with a friend. Tbh I don’t think it would be that long, I think this is all because he’s a baby, and my child’s father doesn’t help with it at all. He just works. He barely takes initiative to even hold the baby. I’m doing basically all the parental responsibilities on the home front. I don’t think I would survive taking care of my infant, the home, dog, and a job. Along with everything else I do. I kinda feel stuck a bit. Also I just started getting into DoorDash delivery just to slowly get out that way I don’t get fired from an actual job for leaving early. Please I’m asking for some help understanding being a new mom, and the things I go thru (what I’ve listed) did any of you go thru this?
