Out of the frying pan and into the fire

Okay, so I have my main computer back, but recently, my parents have restricted my internet access to where I can only have it from 6 am to noon on all but Sundays *Sundays are when I have it full time*, and won't give me full access until I've gotten a higher paying job.  Currently, I'm part time at Fry's.  Now, I actually enjoy it as it doesn't have you remember too much.  Now, a fullstacks job has better pay,..., but there's so much to keep track of, and they have more hours than I've worked in one week.  What they don't see is that I'm not ready for that kind of transition!  They're asking too much of me too quickly!  I'm not ready to face this kind of thing just yet!  Granted, I might be a bit addicted to some of the stuff I like to play *Star Wars Commander, Facebook games*, but the move from Fry's to a fullstacks job, I'm not ready for that kind of pressure.  What if mom and dad decide to move and I end up getting fired from the job and don't know where they're at or can't get the transportation to get to them to get help with finding a new job *still working on my drivers license*?  What if I couldn't find a place close enough to work and had little time after work to relax?  And how long will it be before I can find a job that could I can keep long enough to be able to support myself?  There's just too much pressure for me to handle right now.  So many things to worry about, and I don't know what to do.  If you guys have any advise, please let me know.  I'm getting desperate.
