Is it possible to have your Aunt's number blocked from your phone ? You do not need that kind of discouragement . The first year is the hardest ,be patient ,and keep dong what you are doing . Just maintain with your Mom that you are busy working ect...
Do not be afraid to stand up for what is best for YOU !!! You are now an adult on your own ,figure out what you really need and want personally (not what others impose upon you ) and get busy doing those things that matter to you .
All the best to you !
