Frantically would suggest that your mind and actions do not harmonize resulting in illogical behaviors and responses where the person is more anxious calm would mean that the mind is at peace, the person can think through situations and events and create more logical reposonses
Frantically is like worried/upset/scared/"Where is it?!?"/"OMG NO!!"/anxious. While acting calmly is just Chill/Fine/OK/Peace ect;. Just make this in better words. :)
