Anxiety about leaving baby

Just Needing a little advice. I am currently three weeks pregnant with my second child and I’ve been suffering from quite a bit of anxiety and depression from the thought of going into labor and leaving my 10 month old for three days , he has NEVER spent no more than 3 hrs (IF THAT) away from me let alone 3 DAYS . I don’t want to worry myself sick but I honestly don’t trust anyone to keep him while I’m in the hospital and it’s killing me inside . ! I feel like I’m betraying or neglecting him. He will want his mom and has never been with anyone else . He will not understand and I don’t want to leave my baby like that . I’m really big on staying at the hospital the whole time because I left after Alittle over a day of giving birth to my first because I was so uncomfortable and treated poorly by a nurse. However I suffered from so many health problems that I’ve just recovered from in April . My drs couldn’t figure out what was going on . But I feel I did not take proper precautions when I got home. Such as resting and not running around and doing so much. Felt as if my body was shutting down . I didn’t let my body heal. But I’m not sure I’ll be able to stay the whole time knowing I have my son at home waiting for me . I’m not sure I’ll be able to enjoy giving birth knowing I left him behind ! Someone please give me some advice I feel so guilty and regretful already
