Job (Camarillo)

Hi! I was wondering if anyone knows how to get a job that isn't retail? I've done retail my whole life and I just can't anymore.
I'm good with computers but I see the most basic of jobs ask for so much? Everybody tells me that it's easy but no one I know or have met acutally tells me how .
They all got jobs by friends and family .
I am just confused and really need a job.
I'm not physically strong anymore and just need a job for food and rent and God debt.
It's just been hard.
I've been to all the job fairs and apply with them I go to agencies and they don't respond or ever call back.
It's been already since October and I'm at my last leg here.
Some advice or anything would be useful.
