Anxiety Support Group
Anxiety is a physical condition marked by intense and persistent feelings of distress, fear, angst or dread. General anxiety caused by routine day-to-day stresses usually passes quickly and is experienced by almost everyone at one time or another. However, such feelings that linger over time and are very difficult to cope with, and which lack a clear cause, may indicate...

You took care of yourself by stopping and hanging up phone. You know you are dealing with the emotions, feelings, and thoughts about the conversation. Tell yourself you handled it, you are fine, and you made a decision in the moment.
Anxiety is neither negative nor positive, it is a reaction to the fight or flight or freeze. Hydrate your self, breathe, and calm your thoughts with "I took action" and distract the usual pattern.
Best wishes.
