<human>: I'm a junior in college, and met my friend "Jenny" through my girlfriend. We've only been hanging out for about 2 months, since my girlfriend has moved into my place. Jenny is a nice girl and used to be fun to hang out with, but recently has become very open about her depression, romantic problems, and other issues. Within the past month, Jenny has been texting and calling me about her problems, sometimes on the verge of tears.  

Last night, we were all hanging out in my TV room, and my gf had to go to the store quickly. Jenny and I were going to play a game, but she almost immediately started crying and talking about her past breakup with me. I mostly just consoled her and tried to lighten the mood/change the subject, but she lifted lifted her sleeve and started to show me cutting scars on her shoulders. I was extremely uncomfortable and tried to react as tactfully as I could, but I really had no idea what to do/say in that situation. She started to calm down and we played a few games, and was completely fine when my girlfriend came home.

I've asked my girlfriend what's been going on with her, but apparently she's never heard any of this sort of talk from her. She thinks she's opening up to me because I'm so "easy to talk to", but it's honestly just making me uncomfortable. I've been under a lot of stress, lately, and have been struggling with depression as well. I don't feel comfortable with everything that she's telling me, because I feel like I have enough to deal with as it is, as shitty as that sounds. I've only recently been starting to feel better and this stuff with Jenny has been bothering me a lot. I just want to be casual friends again or maybe not at all.

Can you provide a brief overview of the text?
<bot>: Friend I've only hung out with a few times is constantly revealing deeply personal things to me, how to get her to stop or create distance without hurting her feelings?
