you need to give it time and seriously think everything through. make a list of pros and cons for staying at university and talk it over with your mum; ask her for her genuine opinion and put it into perspective for yourself. think about your future and what you want to do, consider the best route to reach that. if you get to the end of these next few weeks and you still feel the same - you can drop out and do what you'd rather do.
give yourself some space and time to consider what's best for your future and your happiness and consider any alternatives you could take. if the problem seems unsurmountable; find little ways to work through it. eventually, things should fall into place. if they don't? university isn't right for you and you should consider the other routes open to you.
take it slow, don't jump to harsh conclusions too quickly and make the most of this time :^)
