I am having some friend trouble. Any advice?

I'm sorry to hear that your friend is bringing herself down, but let her know that she is beautiful even if she doesn't think so. Tell her there are plenty of single, HAPPY girls (me for example) in school, and she will have more opportunities to explore, enjoy, and pursue her dreams and aspirations than if she were tied down with a boyfriend. Tell her she is not alone, and she needn't feel down. I have felt like this, but I realized that nothing good could come of it. I hope your friend realizes that she has a wonderful friend who cares about her (you). :) Good luck!!
