Hey HALLIEBETH,

Glad you've got good stuff going on, but sorry to hear you're sad.

I have some thoughts:

First, could it be that you're so not used to having good stuff happen that you are unsure whether you deserve it, so you're feeling sad as a kind of punishment?

Second, could you have been expecting more? More elation? Sustained elation?

Finally, are you afraid something bad will happen to ruin your happiness, so you are preemptively feeling sad?

Just brainstorming...
