The answer, which may be hard for you to hear, is that *you* will not be getting a "good IT job" as a sysadmin any time in the near future.
To be a sysadmin, or to qualify for some other "good IT job", you need experience, knowledge, and the proven capacity to learn and adapt. No company (besides a tiny mom-and-pop joint) will be entrusting their systems to a person who has read a lot on websites, but has not accomplished anything. A degree is an accomplishment of sorts, because it means that you are willing to use your resources (time and money) toward your chosen industry. Of course, a degree without a related internship or other work experience is still very sketchy.
If you want a sysadmin job without a degree, then you will have to work your way up through other less glamorous IT positions - like a help desk. This is a completely acceptable route because you will learn a lot in these positions, gaining that much needed experience and knowledge and showing whether or not you can learn and adapt (as a job in the tech field always demands).
Lower your expectations and look for a job in the IT industry that is commensurate with your level of experience and then work hard at it. As time goes by and you gain experience, you can look for other IT jobs that fit your higher level of experience.
You do not want a job that pays a lot for a level of experience that you do not have. You will find yourself overwhelmed by the responsibilities, unhappy in the position, without respect from your fellow co-workers, and wishing you'd taken the longer route.
