It seems I have been creating some problems

According to other people (and from what I have seen in myself) I have been doing numerous things that causes problems, allow me to explain.

-Apparently i'm still selfish when I said I would stop being selfish, this is not a good thing because I promised yet I let everyone down.
-Also I complained whenever I lost, this is me (again) being selfish.
-Apparently I aim for certain people and screw them over when playing smash with my friends. Which is not a good thing because it means I don't like my friends (To me) when people are looking in from the outside. (I am sorry to whom I have targeted)
-I generally try to avoid fights but it seems although I have been semi-causing them, as in a fight almost happens and then it just doesn't happen somehow. There has been one or two occasions that a fight has happened. (I am sorry to whom I almost caused semi-causing fights to and to I have caused fights to)

I would just like to say that if I have been a problem to anyone I am sorry.
I am also announcing that I HAVE to leave, I am toxic to the community itself. (When I feel that I am no longer toxic and that will take quite a while, I will probably come back.)
If your going to reply here keep in mind that I am most likely already gone.

Whoa hold on, what happened?

He got accused of ganging up and targeting someone. In a FFA of all things. I personally don't think he's toxic to the community and I like him as a person. I also like the person who claimed he was targeting them so I don't really know how to feel about this. It could have just been salt. I don't think Nick should feel like he has to leave over this though.

EDIT: On the selfish thing I'm not really sure who said he was being that. I've never seen him display selfish traits before.

Nah, don't worry about it. You're not selfish nor toxic. Generally, if we have a problem with someone, we'll tell them, but that doesn't even matter because there's no problem here.

You're not selfish or toxic, and leaving over this seems like a weird move. 

You're not the problem, or a problem. 

I'm sorry that I've been a prick, and that I have trouble holding my tongue when getting annoyed. But at the end of the day it's a few games that makes all of us feel frustrated, but also have brought us many good and hilarious times. We get emotional in both the good and bad ways. 

A lot of the games have been 3 people free-for-all, a mode where teaming will happen. So the constant complaining about it happening when you lost felt annoying, I should've just said stop, but instead I brought up a thing from over a couple months ago. That's not on you, that's on me being a crappy person.

There's absolutely no need to leave, nor does anyone want you to leave.

I do feel bad about complaining so much though, I'm sorry. It's something I need to fix myself. And at school everyone has noticed a difference in me, it makes me feel like a jerk, a big one too.
But, are you guys sure that I'm not that toxic?

It's not toxic to get frustrated, it happens and complaining is hardly the worse thing to do while you're frustrated. 

Nobody is encouraging or wanting you to leave.

I feel like this song works here

You haven't done anything wrong here.
