I second all of this. There are going to be many people whom you do not get along with and are just outright mean to you. Sometimes you have to address the tension, apologize (regardless of fault) and ask for a clean slate/"redo". The majority of people are willing to do this if you go forward with a new approach. It may be a good idea to do a personal inventory and see if this is a career you truly want to pursue. It doesn't seem that it's a high priority to you.
