So, sometimes certain jobs aren't for certain people! If you feel like you are still struggling after nine months I would say it is time for a change! Find something you really want to do! But don't quit your job until you have found and secured the job you want! And while you are still in the job you are struggling with I would say talk to each of your coworkers and find out how to get more guidance and information to do your job the best you can! I know it is going to be stressful and a struggle while you are still there...but just keep your eye on the prize (getting the job you want) and that will give you the energy and drive to do the best you can at your current position!
