Better to have loved and lost than never to have loved at all. Give only what you can afford to lose and give that freely already having made peace with the possibility of failure, and most of your surprises will be pleasant ones. It’s a balance. You are doing good by others in opening your heart. Continue the practice, and you’ll only get better at it. Stronger in the face of loss. More visible in the eyes of those who actually would love you - by baring who you are so they won’t miss out.
