people are so rude sometimes

Okay, so I'm 19 and a single mum. I have my family and friends full support with this baby. And I've had a few people start telling me I shouldn't be having a baby because I can't afford to buy her all brand new top quality stuff... (I have brought a lot of second hand stuff and been given a lot of stuff new and used) and i can't stop crying like I know this isn't going to be easy but I've cut back on stuff I don't need I'm saving money so I will have extra money in cases that we need it for doctors or anything that pops up! The only reason I don't have a full time job right now is due to me having hyperemesis and I just feel horrible that I can't afford to buy heaps of new stuff for her. Is anyone else buying quite a bit of second hand stuff aswell? Only non-second hand stuff I will be buying is her basinett and cot. I've got her capsule and pram which have been checked by my midwife and they haven't been in a car crash and haven't expired! So I just idk 😩 I'm trying my hardest.
