Girl used to be in love with me but isnt anymore?? HELP

[Obssessed]

This girl started DMing me over Twitter one day about class and gave me her number. We then texted everyday for a month straight. She really liked me and told me that she did, she also told all of her and my friends that she wanted "to be" with me. That all changed last week, when she said she just wanted to be friends(Right out of the blue). She then later went on and explained how she was a mess and didnt want a relationship. She kept lying at first, about how my friends peer pressured her into talking to me, and how she used to like me but suddenly doesnt. She gave me alot of other excuses, like how we have nothing in common, we haven't hung out yet. And She also removed me from Twitter, Snapchat, ignored my texts, etc. I had a few of my friends talk to her and ask her why she did this. She just said "it just didnt feel right". I keep obsessing over this girl, I've been really depressed and hopeless to the point to where I am failing classes for the first time. PLEASE HELP!! Do I still have a chance?? Does she still like me?

Don't be obsessed and move on with your life. Harder said then done.

Move on. She doesn't love you, and I know how that feels. The thing to remember is that you don't mean anything to them anymore, so get on with your life.

Just go and try to get the life running back into your veins. Because she'll never come back. Ever.

she doesnt like you, you cant make her, time wont change this.
