Lately my friend has been sad for a long time. I only noticed last week. I tried to be with her, talk to her and things to keep her from being sad. Ever since she told me that she was sad, she has been avoiding me and ignoring me. I don't know what happened. I feel awkward being around her now she's being quiet. I was told that she might like me, but does that have to do with anything? Like why did she talk to me before all that? Should I just give up on her?
