At 29, I made a career change. While working, I went back to school for accounting and loved it. Now, I have a tolerable career with a very reliable routine I like as an accountant. Unplug from internet distraction, and work on using that anxiety of the future to come up with a plan. Why dont you like compsci (are you having trouble with concepts? Watch videos use the internet for something good, reach out for help). If compsci isn't working for you, find a different skill or trade and stick to it. 25 living with your parents is fine if they want you around. You are in the perfect position to be stable before you take off. Help out around the home, do chores and pay some bills for them, and help out with groceries. In the end, you are saving on rent, your parents are helping you out, and you are helping them out and not making a landlord rich while you scrape by.
