Well,
I treat you like dirt:
For example: I insult you, I hurt you by acting against you etc.
It is well deserved:
It is well deserved that I feel bad for that.
I think that word too is really important here.
1. I feel bad, 2. It is well deserved that I feel bad.
I hope I could help you a bit.
Cheers!
