Not sure what to think

I just found out I'm pregnant (5weeks) and have Lupus Nephritis, SLE. I think the best decision would be to abort as there's so many health risks for being on my meds (baby having health issues) and even just having a baby with my illness. I'm only 20 years old with not much financial support. I'm so scared at how I'm going to cope when I actually have to make the decision to go through with it because I'm already hating myself for even thinking about it. 😞
Has anyone been in the same situation as me? Or have any advice anyway? Need some positivety 😓
