Bad morning sickness and a toddler!

Someone tell me there's a way. I have morning sickness so bad, at all times of the day. It's like the worst food poisoning I've ever had but it's not going away. My stomach hurts so bad, I can't even stand up straight! I was sick with my first too but not this bad, and it never went away for the whole 9months. My son is 13m. I feel so horrible when he's crying because he needs a diaper change and I'm stuck to the toilet. Or when I can't make his eggs for breakfast because the smell makes me throw up and feel dizzy. I work part time so I'm home 4 days a week and I'm home alone. Idk what to do! I can't go another 7.5 months like this! *My sweet boy❤
