Stuck looking for a job

Hi! I'm 24 and registered blind.  I previously worked as a Support Worker/ carer but can no longer do that.  I am really struggling to find a job.  I have started doing some volunteering to gain experience but I was sent home yesterday as I can't see the computer screen and they said it was just wasting my time. I'm just getting very frustrated and starting to lose faith. 
To make it make complicated I could be moving home next year to live with my boyfriend which is over an hour away! So it seems even if I was able to get a job I'd have to leave when we move house.
I'm feeling very stuck, frustrated and confused!
