Annoying Family!!

So my husband is a new doctor (Resident) & im currently going into my second year of law school. 
I have a child I had when I was a child (15) & my husband has none. 
 
We live away from family, just us & the kid. However I have a very annoying/nosey family. The kind that likes to ask questions not because they care, but really because they want to talk about you when your not around..awful, I know! 
I went to see them this weekend and they know we are TTC because of our recent miscarriage & instead of being supportive now they had all these questions about "What we were going to do alone with a baby" 
Ummm clearly I'm not new to this, I had a kid at 15 graduated high school with honors, attended college and graduated in 4 years, now I'm in law school... Yes law school is tough and so is being a parent at any stage in your life. But really what are we going to do? Ummm raise the baby -- the world won't stop! 
I guess I just need some encouragement and insight from anyone who was a working momma or Student, had a husband/spouse with a demanding career & had a baby during the process and is now doing just fine :)
