Maybe you're on your phone too much, maybe not? If it's that bad why not fire you?Does a Chiropractor needs to concern themselves with waste disposal? I think not. You're still there for 3 reasons; 2 hers, 1 yours.

1: you perform you duties to standard
2: she can bully you about petty ********(tell me if I'm wrong, but I bet she makes spiteful personal comments)
3:You're worn down by her and lacking the confidence to strike out (you probably wouldn't let her know you was looking for another job)

If it's it's an abusive relationship, then one remedy is to get out
