Coming from a stressful helpdesk background I would say first don't give up and move back home as going backwards is the worst thing you can do to your career. Secondly depending on which area of the world you live in I would say that University degrees mean's squat over industry certifications/experience although they can be helpful for the first graduate. When I was in your situation I basically took the little amount of money I earned and self studied for the Cisco and Microsoft exams while playing around with Linux. Why would you need someone to show you how to do something when it is written clearly in cheap enough books ??. For Cisco there are cheap lab kits on ebay and for Microsoft exams you can practice by building a complete setup inside the virtualisation software of your choice virtualbox, Vmware, Xen you name it.
You will find that once you become industry certified in a couple of technologies it greatly increases your chance of an interview as most companies require people with the same set of IT skills, once you get in the job you can then develop your talents, build contacts and decide on which technology you want to specialise in. Don't limit yourself by relying on the chance that you will get promoted in one company, take the active step and develop yourself so that many companies will actually consider you for an interview and want to hire you:)
