So I’ve been using bumble BFF to get to know some new girls in the area and I matched this one girl and the convo started as normal she seemed nice. Complimented me too, which was nice and I did the same back. Asked me how I am etc and I replied 
But then she said she was feeling ill with a sore throat and I said ooh I know the feeling I was like that not long ago, it’s been going round. 
So then the convo carries on etc etc and then I said I also have exams so I’m so stressed. And she says oh me too, and I kinda just carried on the convo. Then all of a sudden out the blue she starts saying, can’t sleep well lately because I’ve been really depressed and nothing makes me happy and I feel really isolated. 

And well I feel like I do want to just un match via the app and this is not because I don’t want to listen or that I’m cold, it’s that I too have been feeling depressed but I have therapy and deal with it in that way. And I just feel like I’ve known people like that before and also a girl who was a self harmed and depressed and only ever wanted to drink which made me a big ish drinker and they really do have the ability to drag people down too and I can suffer from a low mood a lot when I’m not doing well, and I feel like if I knew someone new like that then it would make me worse. 
AITA for being like this and thinking about not responding? Or should I reply
