my daughters only 6 month, I don't want another baby!!!

Okay before I start let me say this, I am sorry for you if you can't get pregnant, that's not my fault and it's probably not yours either so if your going to come on here telling me how lucky I am please save it! 
My daughter turns six months on April 8th and we recently found out I am 8 weeks pregnant.... I am horrified and I'll be 100% honest, I don't want this baby.... my husband is supportive and excited and is a stunning father to our two kids but the idea of having a 13 month old and a newborn is horrifying to me and. Idk how I am going to cope.
Abortion and adoption are both not realistic options for me, I'm happily married and we are well off.
I was on birth control and I ebf my daughter... I can't even believe I am in this situation ... can any ladies share some wisdom with me who have been through this or something similar? Please kind words I am already so broken ....
