Expecting baby #5

I was raised in a big family. Only thing is my mom has 6 children; 9 grandkids but I'm my dad's only child. My granny on my moms side has 5 daughters; 14 grandkids and my dads mom has 8 children; 16 grandkids total. I never pictured myself expecting my 5th child at the age of 26. I don't know how to feel about this especially with everyone around me criticizing. I'm stable enough to support and provide for all of my children along with help from my fiancé, but baby #5 was totally unexpected and I don't know how to feel about this. I've been so depressed to the point where I don't even like to get out of bed lately. I was told that in Florida, you can't tie your tubes until you are 25 or have at least 4-5 kids already. I tried to get mines tied after my last baby in 2014 but my doctor said I wasn't able to at the time. That's crazy,,,now I'm expecting again and I don't think I'm ready 😩
