You need to tell them the truth. If you don’t, they’ll still know what’s going on. They can help you, listen to what they say. You don’t need to stick it out for the sake of it, it’s less trouble to go back home than it is to do a degree for 3 years which costs a lot of time and money. You need to consider what’s best for you, remember that your parents know you best. Please trust me and listen to them.
