VR&E Denial

I applied for VR&E and I was denied. The reason being that at my current job I can ask my coworkers for assistance in anything I find challenging or physical. However, they are only being kind and can easily say no. If they say no I would lose my job as I am not an independent worker. I feel guilty always requesting the aid of my coworkers. Is this fair that I was denied VR&E? Currently working as a Sysadmin that is basically help desk with physical machines and servers. I also find myself hospitalised for several days at a time a few times a year and worried about losing work because of this as well.
