Try typing work oneself up at www.dictionary.com
Please help me find alternatives for the phrazal verb in red:
Calm down! You shouldn't work yourself up into such a state.
I'd like to know what other phrazal verbs can be used in such situation.
Many thanks in advance!
To get angry, to make oneself angry.
Lash oneself into a state/a rage/fever
Drive (e.g. Drive oneself to distraction; Drive over the edge)
These are not strictly speaking phrazal verbs, but they're alternatives alright.
