What am I doing with my life?

Dear bloggie, I'm feeling down and insecure. Should I give up? Sometimes I look back at all my hardwork towards the relationship and towards him, I wonder.. Why am I working so hard for? Why do I give my heart and soul to someone so immature? I want to be love. I need the support from a man I love. I know all this yet why am I tormenting myself? Who will love and support me? Maybe I should give up and stay away from humans. I don't want to be hurt anymore. I'm tired.
