Constantly Missunderstood?

Recently I feel that I have been constantly miss understood and have been ostracized by over a dozen people around me. I have lost several friends and even kicked out of a cl that I love. I am 33 and never in my life has this ever happend to me. I have never been kicked out of anything before and the last time I lost a friend was in High School so I'm taken way back. Over all, those people who know me would probably say that I am very positive, funny and extremely easy to work with. But I have just started working with a new group of people and none of them seem to like me and they definately don't respect me in any way. They mistake everything I am saying and I feel like I'm constantly saying "I'm sorry" and having to explain myself. I am walking on eggshells and that fact that I'm walking on eggshells seems to bother them too but if I don't and let myself go like normal they mistake everything. Some of them don't like me at all and I really have no idea why but I have asked and they attack me as though I'm stupid - which under normal cirstances I would say that I am not. I'm very confused and I have tried talking with them, showing them them nice side, just kind of being me in the most positive way and nothing works. I have tried the "I don't care" and be strong but I'm paper thin. I'm so confused. I've never had this many people judge me so harshly, so negativitly and hate me so completely in my life. Any suggestions?
