This! This is perfect, and absolutely the truth. Your feelings are valid and true, regardless of how someone else sees them, and you are allowed to feel however you feel, even if it doesn't make sense to the rest of the world. For what it's worth, I think you have the right to be mad. Your cousin's response seems dismissive, and during a hard time, that is the last thing you need to hear. I hope you have other people around you who are able to be there for you, in ways that you need right now. Take care of you, and ignore the a-holes.
