It sounds like you are overcommitted. Before you drop out of uni, at least try putting the driving lessons on hold, and unless you have no choice financially, cut your work hours right back, preferably to nothing during term time. Full time university study is equivalent to a full time job, and not an easy one. Your university can't make extra hours in the day for you - if your main problem is that you feel you don't have time for everything but it's because you have taken on so much extra stuff that you actually don't have time for everything, you don't need help (at least not as a first stage), you need to reduce your commitments so that you do have time.
