How often do you have a difficult conversation?
What makes it "difficult", exactly? Is it because you don't know what you want to say? Or is it more because you don't know how the other person is going to respond? And what do you make it mean when they respond a certain way?
I find that mindfulness and self-compassion can be very helpful in such situations. When you stay present, you can focus and listen to what the other person is saying. What they are actually saying, not just what you think they are saying. There is a difference.
When you are kind and understanding to yourself, you remember that you are worthy and enough just as you are. The other person's response may be unexpected or hurtful but it is more a reflection of who they are in that moment as opposed to who you are. Maybe they weren't expecting this and have been having a bad day. We never know exactly what is going on. Not taking things personally is a huge part of emotional resilience.
And lastly, remembering that we are all human and we are in this together. Everyone goes through ups and downs, light and darkness, happiness and misery, love and loss. Life is a cycle and these are all opportunities to grow stronger and evolve. Sending you so much good energy, always.
