If you are having conversations with individuals, and feel drained of energy, it may be because a demon is standing between you and them. Prior to beginning any conversation that you know will include talks of repentance, speak in the language of the spirit, and behead every demon in, on, and around you.
Ask the other person to do the same. Also, behead every demon waiting above you, and above them. Finally, behead every demon standing between you and them. The conversation is likely to be much more productive.
