Regardless of how new you are to the game, nobody has the right to harass and berate you.
Report the people who do so with great prejudice. Report them several times over if that is what it takes.
Most of all, don't let them get to you. Stand up for yourself and stand up for others.
There are some jerk players out there but in no way are they the majority.
Unfortunately, they are the loudest.

Still, I'm sorry that this happened to you OP.
Shame on the rest of your party for not saying anything to the tank.
