Glad to see a question like this on here, frankly. I'll just simply add my .02 and share about my trajectory, as I shared a similar dilemma close to 6 months ago, but have began to move forward as of late. I began looking for work in just about anything IT related (even though my overall goal is info-sec). I began a Bachelor's Degree program in September, majoring in Cyber Security. It is a relatively new program my college offers, and so far is great. Since I have began this degree program, many doors have started to open. Companies I would apply for prior that never called, are calling.
I had a CCNA in 2004, and it obviously expired along with some of the implementations of that time period, but companies still love to know I had it at one time. Never be shy about putting something on your resume, no matter how benign. I have an interview next week with a very high level disaster recovery center, and as soon as they read that I checked 'yes' to the "Proficient in the Linux command line yes[ ] No[ ]" question, they left me a voice mail and an e-mail a day after I applied. But like you, I also have no formal on the job IT experience, but slowly that looks like it is coming to fruition. So hang in there, and keep swinging. I also agree with what others have suggested about trade schools not being all they are crocked up to be.
