What do you do when you have to medicate your bunny a lot and he/she seems to hate you?

Roger is a middle-aged bun who is currently on something like 8 medicines (ears, digestive, dry skin, eye, mucus/snot). He's a pretty fussy bunny anyway, and it's a real struggle spraying him with two different sprays, doing ear drops, eye drops, wiping the eye gunk off with medicated cloths, giving him two different mouth syringe meds, and putting an additive in his water (most of these things TWICE a day).

The problem is, I work long hours, so I get up, medicate him, go to work for 10-12 hours, come home, medicate, then try to do more work and household chores. I feel so bad because he is afraid of me now. I am trying to do some of my work sitting on the floor near him, so he doesn't feel like me being there = icky medicines, but I don't think it's having the desired effect. I even think my other bunny is mad at me too! When I try to pet them, which they normally like, they both run and cower under the bed.

I feel like a monster! Suggestions?
