Please don’t abort unless you are certain, especially as you suffer from anxiety and depression. An unwanted abortion could really have a negative impact on your mental health. Everyone is struggling with money at the moment - I have 2 and honestly 2 is not much more expensive than 1! I always wonder why people make out like it is a big price increase because it really isn’t in my experience.
Re: your daughters issues, I had similar concerns about my first child (a son) that you have about your daughter (similar issues). But you daughter might adore her sibling and they might help her learn to engage with other children better, your daughters sibling might be the best friend that she needs! This is exactly what happened with my son who I was worried about - his baby sibling became the absolute light of his life and his best friend when I’d been worried about him being lonely before, due to his issues. He’s never lonely now.
There’s a good reason - or several good reasons - to end every pregnancy, the timing and situation is never perfect. It’s not been for anyone I know, anyway. Or me! It’s always money/relationship/career/home issues. A baby might make these things more difficult or put you in a less than perfect situation for a while but that’s life, things will improve. And you’ll have another child who you’ll love just as much as the first who will definitely be worth the temporary inconvenience and the struggle.
FWIW I also suffer from anxiety/depression/ADHD and I was worried about my transition from being a mum of 1 to a mum of 2! Honestly, I was SO surprised by how easy it was. Baby number 2 is a breeze compared to baby number 1 (anxiety wise) because you’ve done it all before and you know how tough they are and they just sort of slot into your life - you just do what you did before but with a pram or a sling! And when baby is older it’s even better because the two can play/entertain each other.
MN is always so ‘yes you should abort’ whenever there is a thread like this, and I’m just wanting to come on here to show that I too was in a very similar situation and I’m so glad I didn’t abort.
Good luck with whatever you decide. Your decision matters most so don’t be pressured if it isn’t what you want 💐
