I'm pregnant and I don't want the kid

Okay I know I will get hella hate for saying this but I want an abortion. I am going thru way too much to have a 3rd child rn and I'm terrified to even think about having another kid. So is there like anti e who can talk me thru this. refer me to clinics. I'm pretty sure I'm only 4 weeks so I would have to wait a couple more weeks before getting it done but I can't physically or mentally have another child. And I can't just go thru 9 months of pregnancy and just give the baby up.
