My so called friend is all ways down on me. She makes me feel really upset. If I tell her something she runs off and tells someone else what should I do?
Do you really think you can trust her. I don't think so. Stop telling her personal stuff then, but you could continue being her friend. But trust is a real issue here, and being careful is all upto you :)
Maybe talking to her about it could help or even something as simple as just ignoring it could do you good. Try not to trust her with some things like certain secrets and if she makes you feel upset, hanging out with other people is another option...
