Nosy family

I don’t understand why some family members have to be all nosy for my mom texted me this morning and asked if my fiancé only gave me 200 dollars out of our dead newborn tax return this year he ended up passing away back in December a month after having him we got to claim him on our taxes this year since he was a live for a month. Yes he gave me 200 but the rest of the money is being put towards our house we are getting to get new flooring lay down and we have to fix our ceiling plus paint pretty much everything I don’t see why my mom thinks it’s her business or my sister business to tell someone I honestly can not deal with it so much drama in my dang family I am ready to move away just to get away from it. I could care less about getting my dead sons full tax return because he’s clearly not here where I could spend it on him I am not planning on blowing it on myself I would rather put it towards our house we have been waiting for when I was pregnant with my son.
