Sounds like you need to speak to a therapist, your course/department convenor and also your friends. If you think you will be in a better state of mind later on to deal with the course, you can ask to defer your degree until next year. If you really don't think you can handle it, it's better dropping out now so you don't have to pay any of the fees, but it could also be that your current state is what is making you think you won't enjoy the degree, and in a clearer state of mind you might be more determined. This is where contacting someone in charge of your course will be useful, they'll be able to talk you through the options. But prioritise trying to get mental health assistance if you're not already, it really does sound like you need it.
