Abortion after first child at 17

I'm 17, I already have an 8 month old son who will be 9 months on July 27. I have the Paraguard IUD and that is the only birth control method my boyfriend and I have been using. I just found out I was pregnant a couple hours ago and I know I have to have an abortion. We just got our own apartment and I'm only 17 for gods sake I cannot be.a mom of 2 by 18 I would go crazy. I suffered from ppd for months and I never really got the help I should've and I still feel like I'm suffering from it. I'm only 5 days late so I'm super early thank god but I'm so heartbroken. It's birthday would be in the same month as mine and you know, what if it's that girl my boyfriend and I want so much (later in life obvi). I know what my decision is but I'm all sorts of fucked up about it and I just needed to rant 😔
