Help me with this. Please.

I have a 1 week old. I EBF. She does not sleep unless held. I can’t stay awake. I fall asleep with her in the chair. I tried feeding standing up until I literally dozed off and startled when I started leaning forward. I nap during the day when my husband takes over, he isn’t home at night to help at all. It doesn’t matter how much I sleep I just can’t stay up.

I think I have postpartum anxiety. Since the day we brought her home I am bawling worrying about her dying from SIDS or suffocating at night. Because of this I don’t want to bedshare. I know about the safe sleep 7. I brought her in bed with me the other day at 5am after 20 minutes of sleep all night thinking maybe it would be okay and I started awake while feeding with my boob over her nose so I’m afraid to do it again. I have a toddler who I’m afraid will crawl in the bed and I won’t feel him there and he will hurt her. I have started hallucinating during the day and I feel like I’m going insane😞 I worry myself sick at night and cry scared she will not make it through the night and it will be my fault. I carried her, birthed her, now she’s here and she’s my world..I don’t want her taken from me. I can’t lose her.

Please tell me what you would do in my position.
