I made a HUGE mistake.... i finished the dawnguard and normal storylines really fast so i just went around on a killing spree for no aparrent reason? well in that spree i ended up killing constance michel. So if i did that bassically i cant adopt children anymore right. Cause i bought 2 childrens beds and when i ask to adopt them it says i have a house but no room for you even though i have 2 childrens beds? i dont know what to do... I AM SUCH AN IDIOT. can someone give me some help or info. ill really appreciate it.

There are kids around Skyrim you can adopt. Just keep looking.
