Need Help! Abortion??

Ladies im 26 Years old and I have a almost 4 years old and a 1 & a half year old baby girls and I love them with all of my heart. They were planned and we are happy to have them, my husband and I had decided to have our 3rd and last child when my youngest girl turned 5 but we found out bought a pregnancy a while ago honesty I dont feel ready for this, I've been feeling depressed and anxious since my last pregnancy and now that I was starting to feel myself again I found out I was pregnant I feel like a bad mom because i wanted to enjoy my 2 girls, my husband and I are going through a very bad financial situation and I just feel like this is not the time for us to have another baby I have not family to help me, I'm always by myself and now with 3 I don't know what's going to happen. Been thinking a lot about an abortion but I don't know what to do 😭😭😭 just feel like the worst mother..

And yes I know I've should have taken care of myself before I got pregnant......
