<human>: Been with a girl I'm really into for about a month now. We have pretty good communication but everything still feels so new and fresh. We both probably have things about our past we haven't shared with one another yet. At what point (if ever) does it make sense to bring up stuff like this? In my case it was personal struggles with depression/body image/food issues, some unhealthy relationships in college, etc.

I feel like it's part of who I was and may still be a part of who I am. And I care a lot about this girl. But I also don't want to be bummer of the year and bring everything down.

Can you provide a brief rundown of the text in within 3 sentences?
<bot>: When to bring up troubles of past (if ever) like pretty bad depression/pretty unhealthy relationships? What's oversharing?
