<human>: Could you distill the essence of the text into 1-3 sentences?

This is a little hard to explain.

I'm a very non-threatening person. I'm a 5'1 20 year old woman. I have a soft voice and I guess empathetic features or something. This is pretty much the only reason I can think of that I keep attracting people to tell me all their woes. 

Every time I try to make a friend, the conversation turns from "so the weather's been really nice" and "oh, you know Ben too?" to "Yeah, my dad sexually assaulted me when I was 12" and "My mom died of cancer two years ago and I started drinking because of it". I swear to god I don't do this on purpose. I try to talk about light things, and somehow it turns dark and I just sit there and nod and say "oh, wow" because I'm completely at a loss. What are you supposed to say to shit like that? I guess what I'm doing is fine enough because they always keep talking. 

This happened with all my friends in high school. It happened with my roommate in college. It happened with my lab partners in science classes. Every time I spend more than 10 minutes talking to someone, they tell me *everything* bad that's happened in their lives. It's never just one thing. They tell me about everybody who died, about all their medical problems, pretty much everything that you'd think would be at least a "second conversation" secret. 

This is really taking a toll on me. I'd just like to have friends who I can shoot the shit with and talk about silly nonsense. My idea of a fun conversation would be talking about Doctor Who and what's been in the news, not about how someone's schizophrenia has ruined their relationship with their sister. This is going to sound heartless but it *really fucking bums me out* hearing everything bad about somebody's life. I have depression just on my own, and this isn't helping. 

What can I do about this, besides just giving in and becoming a therapist? I don't want to be an asshole and tell people *not* to trust me with their secrets but this blows.
<bot>: For some reason everyone I meet feels comfortable immediately telling me their darkest secrets. I DON'T FEEL COMFORTABLE HEARING THEM. How do I dissuade this without being an asshole?
