What I've learnt over these past few weeks is... There ARE going to be people who will not 'be there for you' after all. And I can choose to use those people as my example that, "See, I knew it! It's better not to trust anyone because people only lie."
Or I could say, "Look at the people who promised they would be there for me, and you know what? They were... Always. Just as they promised." And I can use that to change my view to "I can trust people again."
Deeply grateful for the people who kept their promises in my life.
