Hopelessly hopeless

This is certainly the darkest phase in my professional life. I've been ridiculed, insulted, harassed by my seniors. They say that I'm lazy, lethargic in work and I've no sincerity or honesty in working. Irresponsibility, rudeness and apathy are the other terms that I've heard about myself. I know that I'm partially to be blamed for what happened as a 'cause' to all this. But this hurts me. I'm now the exact opposite of what I wanted to be. I don't know how I'll make it through this phase.
