Opinions 🤔 ( no rude comments please )

I am 18 years old and I have a 5 month old son I'm considering moving out because I feel like now that I'm out of school & have a child the relationship I had with my mother is different she isn't mean or anything it just seems like we're always bumping heads I'm just worried that I won't be able to do It on my own ( I only make $11 a hr ) 🤦🏼 my grandfather would let me live in the home he plans to leave to me the only bills I would have to pay are lights & water but I'd also have to buy extra things like gas , food diapers/wipes etc. I'm just so scared that I'm going to not be able to do it alone 🤦🏼 have any of you done this ? If so could you share your experience.
