That is a lot of time to give up and start again and it seems that they want you to go as you are caught in a vicious circle at this time,Target does not want tms who are obviously miserable to be there,so unless you can get you head right,you really should move on,it is only a job so why be miserable and fighting with yourself to go in,personally I would not go in for four hrs anyway.as suggested above loa would give you some breathing space,good luck.
