I Hate Myself

If he cares about you he'll be understanding... No one should expect their date to be a 24/7 source of joy and cheerfulness. Mind you, I think any reasonable guy would appreciate being "your rock", someone you can lean on and trust with your darkest feelings, etc. In my opinion, just having the opportunity of going out to eat something with you would be a privilege, and I think the onus is on him to steer the conversation towards things a little more specific than "tell me about yourself". If you feel the date went terribly wrong you may text something along the lines of "sorry, I was not in a good mood today", etc. If he's a worthwhile person he should see all what you are, past your depression...

Yep because I’ve got it too.
Churchill had depression and described it as a black shaggy dog that follows you everywhere.

It can be difficult. But it doesn’t mean you’re a bad person or damaged goods. Talking about yourself may open up some discoveries. And one might be that the qualities that you thought were awful are actually what makes people like you. Being yourself and human is the best quality of all and one we can all identify with.

People won't understand.. unless they have fought the noon day demon themselves. It's all academic and conceptual unless they have drown beneath an ocean of sorrow and choked on the darkness of a thousand deaths. So don't bother explaining unless a relationship gets really serious.

Are you even ready for that level of conversation?
Maybe that isn't where you should be right now, mentally?

Discuss music and food. Look how well that works here!

I'd love to say it get easier but it never will
