Times are uncertain. Stay put for now. More work exp under your belt the better. Most people in IT have to 'pay there dues' at the help desk.
To stave off insanity try to find other hobbies that have nothing to do with computers. When your hobby becomes your job you start to hate your hobby and lose it up there.
When I went up to Sys Admin I can say my job is alot less stressful but there's usually someone phoning or emailing you with something mondain.
IT usually has spots of insanity. No matter what level you get to. I waited 3 years before finding another job. If your current employers treat you ok you should probably stay put. Bide your time and keep an eye out for a better position. Quit AFTER you sign papers. I cannot stress this enough. IT can be very cut-throat, especially in small cities / towns. A shake or verbal contract is not enough. Wait till that ink is dry.
Maybe see if your company can help you get certified. Might as well learn something while your biding your time.
In finishing, get a hobby that doesn't involve computers this is important to your sanity. I bought a jeep and took up 4x4ing with a local group. Also took up mechanics,to a lesser degree.
