First day home

I was induced wasn't a bad labor at all, felt like forever lol as most do. Well I have a soon to be 4 year old son who at the moment is staying with his awesome grandpop (thankful for that) which he comes home tomorrow to meet his new little sister I'm so nervous because my ever so helping boyfriend (daddy) is going back to work so soon 😞 and I'm so scared to do it alone still have a little hard time using the bathroom and with my son coming home I need to show him just as much attention as I do to our little girl. ... I get so scared thinking about it I can feel tears build up but I don't cry because I don't want to cry in front of my boyfriend. I don't want him to think I'm being a big sissy even though he knows what I just went through with labor. Any advice? From other mommys who have went through this with little to no help ? How do you stay strong? What do you do to cope with it .. I never had postpartum with my son because my mom was always there with me to help
