The best advice I can give you??

If you can only work 4 hours and are incapacitated for days after.... that's your brain telling you to stop working.

Now, as a grad student myself and someone who just had to leave a full time job for the same reasons, I understand your fears and concerns. How to pay for things, how you'll survive when you start Grad school etc.

However, if you don't make your brain's recovery the only priority, (which may mean not working and financial struggles), you may increase the likelihood you won't be participating in your classes this fall.

I know it's a scary thought to not work, because it leaves everything up in the air. However, I tried to go back to work and had a complete relapse of symptoms and feel like I"m back to where I was months ago. I too would like to be able to start classes again in the fall, but I haven't even been able to go back and finish the end of the spring that I missed when this all started.

Sorry if these seems like tough love, but if you dont' take care of yourself... Grad school will be irrelevant because you will still be too sick to go.

I wish you the best and speedy recovery so you can continue on with school and get back to work quickly, but honestly the best advice I can give is that if work is triggering PCS, then you need to stay away from work for a while.
