Hi, @Meeko93, I'm so sorry you are having such a hard time, and agree with other posters you should make an emergency GP appointment as soon as possible to discuss help and support.
Obviously I'm not a GP, but based on what you've written, I would be thoroughly exploring whether you had Antenatal depression before going down the irreversible route of a late term abortion.
Antenatal depression is not often discussed, and is a taboo subject, ( there is a societal expectation to be "happy," during pregnancy), but it is actually much more common than people realise. A fear of life changing, combined with hormones your body has never been exposed to before, and pregnancy symptoms such as sickness/ nausea / exhaustion can lead to panic and "what have I done?" feelings. I fear that as this was a planned pregnancy, you may regret a termination very much once the pregnancy ended and the antenatal depression lifted as the hormones subsided and the reality of the abortion sunk in.
Are you taking antidepressant medication now ? GP's can and do prescribe antidepressants that are safe to take in pregnancy on a regular basis.
PANDA's are a UK based charity that have a helpline running until 11.00pm, and are designed to support people experiencing prenatal and postnatal depression.
I'd suggest you contact them tonight, and make an emergency GP appointment in the morning:

Take care,
