I was sick every day until my son was born and anti emetics were not helping. I remember feeling exactly like you.
Id tried everything and people kept suggesting the same things over and over like they were being helpful but it just made me feel like they thought I was stupid because who, in this situation, hasn't already hit Google to find every possible remedy.
I was pleased as punch when they said my son was breech and organised a C section because the moment he was out I felt normal. Literally that very second.
But I remember feeling like you, and considering abortion.
I have no practical advice. You need to do what's right for you. But you're not the first person to have felt like this and you won't be the last. Solidarity.
I will say. I'm glad to have had my son. I did have some postpartum depression and didn't really feel bonded to him when he was here but he's made my world infinitely better.
At the time it didn't feel worth it. But seeing him now, it is.
In a years time, where do you see yourself with and without a baby? And which option makes you happier?
It's hard to think about the future when the now is so shit. But don't make this choice rashly. Have a good think about it. Talk to a counsellor. Write down ways others can be more supportive to you. Don't be scared to ask people for help.
Wishing you all the best.
