Perhaps University is adding to your stress as the support you had at school and perhaps at home is lacking. First year can also be a bit uninspiring work wise.

Young people at university are rather vulnerable to setbacks, but it need not be that way. Universities have counsellors to help students with the very common difficulties of adjustment - there is no shame in seeking help and in fact you might say you deserve help. After all you did well to get into a good university and the course you wanted - it is not easy and can come at some psychological cost.

Try to think on the positives - you may be skint and have some demanding work to do with a short timescale and little support, but it is interesting, you have more freedom than you will have later in life, lots of similarly young people and there is no rational reason to suppose you cannot do well.

I would guess on not much to go on that seeking help and toughing it out to the next holidays to see how you feel is called for here rather than quitting.
