Well, alot of people on Feral Heart do have low self-esteem and will try to feel better by starting fights or harass others. Just because it's Feral Heart, doesn't mean there won't be bullies.
Also, Feral Heart is a game so remember not to take it personally. You will be surprised at how many people couldn't care less about having you 'there', the best thing to do is surround yourself with people who know it's a game and don't take it harshly. The perfect example happened to me a few days ago. I was in a pack of awesome people, but frankly I couldn't stand the drama they started. So I left, and no one - not even my friends in that pack bothered to contact me.
People on the internet are not what they seem to be irl. Not saying that you shouldn't have friends, but I'm saying not to take anything to heart. Anger is easier to take out on anonymous people, and frankly it's your decision to take or ignore it. Feral Heart was made for fun, not stress.
In the end, you decide who you choose to stay with. Of course this will happen, but the best thing to do is move on and find more friends. It's just a game, after all. No need to waste your time or energy on those who want a fight.
