I feel like such a shitty mom

So 2 days ago I was feeling lightheaded, couldn't quit puking, and fell like i was gonna pass out alone with my 11 month old. I ended up having to be rushed by ambulance. I stayed there until about 2pm and got discharged. I made it about 40 minutes and I got tingly, lightheaded, froggy, nauseous, etc. So I called my doctor and she told me to head to the nearest ER. So I did, stayed for a few hours and got discharged. I didn't even make it home before I had to have another ambulance bring me right back. Ended up staying until midnight and was sick all day yesterday. Well hubby went back to work this morning because they're threatening to suspend him for a week since he went to the hospital with me. I'm home alone with my son and I don't feel ok. My body is so weak I can barely even lift him let alone tend to him. I can barely get off the couch and I feel so guilty. I'm such a shitty mom 😭

UPDATE: I've puked 6 times today. All of my symptoms (shaking, extreme nausea/vomiting, dizzy, froggy, tingly all over, etc.)have returned. Almost passed out so I called hubby at work and he told his boss he had to rush home. His boss started downgrading me and said how I'm not very resilient. So hubby yelled at him and ended up getting permission to leave. I'm worried because this exact same thing happened to my aunt and Grammie and they both got hospitalized.
