So it's winter break and I'm trying to start talking to and hanging out with new people. The group I'm hanging out with right now just seems to be getting bored of me. My closest friend I message everyday replies to me with 1 word or really short replies no matter what I try doing to get her to properly talk to me. The only time she properly talks to me is when she needs to talk about something like how she just broke up with her boyfriend, but when I try talking to her about our once close friend we don't talk to anymore she completely blows me off and says she doesn't care. I've tried talking to her about how upset I am about things, but to her it doesn't seem relevant. She makes me feel like a loser because she's always talking about how many people she messages and I basically only talk to her and a couple other people on and off. I want to stay friends with her, but our friendship seems to make me sad more than happy and I feel like most of my self worth comes from her. I could be sitting there for half the day not talking to anyone and feeling like a complete loner, but as soon as she messages me I feel like I have some worth to me. I know this isn't healthy but I can't seem to change it no matter what I do.
