I mean this in absolutely the kindest way possible, but I’m not the greatest with words, so I apologise if it comes across wrong.
You say you have anxiety problems - I think pregnancy will always exacerbate these. There are too many unknowns. Nobody knows exactly how their pregnancy or labour is going to go, nobody knows how their baby is going to be.
One thing I do know is that the situation is rarely static. Babies turn into toddlers, who turn into pre-schoolers, and before you know it you have a teenager...
Although sometimes it feels like these phases are lasting forever, they will inevitably end, and the next one begin.
There will likely be phases where you’re on your knees, and phases where you’re incredibly happy. The fact is though, that you won’t know until you get there, nobody will.
I’m struck that your anxiety seems to be more a general one about fear of the unknown rather than of anything in particular. A lot of “what if’s”.
But I will say that you seem to be thinking you’d rather live with a choice you’d regret, than risk one that your child may regret. That says a lot about your feelings towards your potential baby - that you are already thinking about their needs above your own. And that’s the crux of parenting really - you try your hardest to fulfil your child’s needs before your own. (Doesn’t mean neglecting your own by any means, btw!)
I’d urge you to seek help with your anxiety. Not just for the immediate now, but long-term, whatever your decision about this pregnancy is.
