回複：慘重教訓，我隻有走路了嗎？

Sorry to write in English.
No worries, you should not plan to leave unless your boss said so.
Yes, first job is the most difficult in terms of interpersonal issues (people tend to "screw" the innocent new one).
Suggestion for now. Go check your job description and make sure you do your job well. Do not let the way other people treated you steall your joy of doing your job well. About work, if people ask you to do their job, do not say much to them but, have a conversation with your boss about this. Make him/her aware of the situation and how do you plan to deal with it AND remember to make a point NOT to say too much negative things about others. How to deal with that woman - pulling up distance from her politely. Do not let her acting out - if there is no issue in your part, make sure YOU express it regardless what/how SHE says/does.
General advise for a new job - keep your eyes open and mouth shut.
Step 2 and long term. Keeping in mind that you are by yourself in this world, watch out for yourself all the time. It does not matter what other people jerk you around - clarify your job with your boss and do it well. Inform your boss when you do not do OTHER people ask you to do.
No worries, you should be okay if you practice these for a couple of weeks or months. Just do it.
Hope this helps.
