Hello "Vada" I am so sorry to know that this person has brought so much negativity in your life. It sounds like he has made a real effort to single you out and make your life hell. The worst thing about bullies, and I do believe he fits the term perfectly, is that they keep beating you down until eventually you wonder if 1) they are right about you, and 2) you have no self-esteem left. One of the worst things I see here is that you have isolated yourself from your family. This is the worst thing you can do.
I would certainly recommend what the earlier post said about beginning to document each and every incident. Recording him is also a good idea as long as this is legal. I know in some places it is not. Try also to document as many earlier issues as you can. There must be someone close to you, a friend or family member whom you can confide in as well. This will help give you courage and confidence that you need.
No one should have to work in such an environment. Consult an employment attorney to find out what your rights are. I must tell you that when I was 20, I was sexually harrassed in a job I had, but did not have the courage to stand up for myself then. I truly regret it because that man was a true pig to take advantage of my inexperience and youth. I have also dealt with bullies at work and I truly recommend that you no longer allow this situation to continue. It will eventually change the person that you are.
God Bless you and please keep us updated as to your progress.
