You should read Sun Tzu’s The Art of War. And study it hard. You won’t be terrorizing the weak minds around you for fun anymore. You will think like that Chinese warrior did thousands of years ago. Read up. He was Gen. Patreaus in his time.
Good advice! There are many translations of The Art of War. I remember one book that has his text and then someone wrote essays about how Sun Tzu's philosophy can be applied to contemporary situations (your job, relationships, etc.).
The people who post that you should have documented everything to prove to your tormentors that you are right and they are wrong in order to make them be fair is completely wrong. You cannot expect to convert people and make them act fair. Life is war and you cannot fight the machine on its own terms. Although it may be too late for your job, you can apply this idea from Sun Tzu in the future - use your enemies' resources to your advantage. For example, if you are in a job where people are abusive but you can get marketable training and experience, then you can take the training they paid for and eventually get a better job elsewhere.
Do try and see if you can get unemployment. It is possible that your former employer has a bad reputation about unemployment claims and they might not even fight a claim - it is worth a try. I know people are telling you how simple it is to not accept abuse and how easy it is just to find another job, etc. I know it is difficult, especially when such a "change" is forced upon you. I have lived through some very precarious situations and I know it is not easy. I have been in situations where my enemies treated me like a doormat but at the same time I used them (or rather, their resources) as a stepping stone to a better job. It was hard to hunker down and be quiet while I saw unskilled people promoted over me. It was hard, knowing that I was very productive and did quality work while I was being taken for granted and slackers were rewarded. And it was painful to temporarily accept abuse, even knowing that in the long run those people were nothing to me and I would soon free myself of them. Someday you will be so glad to be free of those jerks but I know now that does not put food on the table.
