Dolfin,
Have you talked with the people around you at home about what's going on? I still think you need to get outta there, being bi-polar only makes it harder to cope with these problems.I understand you don't want to give these girls the satisfation of quitting, but i'm sure this atmosphere is affecting your social life and relationships. I say Get Outta there. These girls don't care about feelings and management doesn't either. Get Out!
