Looking for another job is a good choice, and while

you are looking, make an effort to improve your current position by changing yourself. The difficulty you are facing is also an opportunity for you to improve your soft skill. One thing we have to learn is to put on a fake smile even when we are down or unhappy. Being positive regardless the situation is always a better choice than being negative. This skill is very helpful but not many people master it. Afterall, it is always easier to change ourselves than to change others, right?
