How can you feel guilty for something that you didn’t do? You just exist. It’s a fact, not something that you had any control over. If you really think your words through, I think you will realize that not everybody would have an easier life without you. This is not logic. This is the cruel inner voice. I don’t think you should listen to this voice.
What happened? This doesn't sound like you. Thought things were better? You offer so much life and joy. You are very creative, and sensitive. It's difficult for sensitive people. Not a easy path.
