When Does Banter Become Abuse?????????

Please! I need advice! My friend call me inbred and i think its funny sometimes but then it hurts! I need to know when i the banter becomes abuse! My life has no more meaning.. if i am really inbred, and everyone (even my parents) hate me to the bone.... I might just end it all now. I need to know someone out there loves me and wont abuse me... please.
