  • I don't see the point in living anymore?

    I just don't. I did bad in school last semester, so I'm retaking my classes this semester. I'll probably fail again. I'm also going to be alone forever, seeing as no guy ever wants me. So whats the point? If I never have a family or kids or someone that loves me why should I be here?

  • Sugar Glider............................?

    So I got a sugar glider, literally 20 minutes ago. It's a little girl and she's in the pouch in her cage, and I've fed her some apple but she keeps trying to bite. I know she's probably just scared but I'm nervous lol I don't want her to hate me forever. . What else can I do to bond with her. I figured I'd talk to her through the cage and then get her out in her pouch when she calms down. Advice would be much appreciated.
