Is it possible that I am noticing some peope getting mad at me for the fact that I control myself not to loose my cool, avoid fights and do not seem sucked by the discussions they try to start?

Yes, absolutely. When you work on yourself and control your anger, avoid fights, and refuse to be drawn into pointless arguments, it makes other people extremely uncomfortable. Why? Because by restricting yourself and being happy about it, being confident about it, being proud of it, it makes people question themselves, and they don't like to do it. It makes them feel uncomfortable, so their own insecurities cause them to lash out. Most people today have zero restrictions on their behavior. They don't restrict anything. They're like animals with no boundaries, no control. So when they see you controlling yourself, not getting angry when they're trying to bait you, not engaging in their nonsense discussions, it actually reminds them of their failure. It reminds them that they are spineless, that they have no self-control. Subconsciously and consciously, they know that what they're doing is not right, but since they're surrounded by people more like them than you, they're comfortable with their life. And you make them uncomfortable. This is especially true if these people used to know you before you started working on yourself. By looking at you becoming committed to controlling yourself, to having yirat Shamayim, to having these restrictions and limitations for your own good, it actually reminds them of their failure. They may even acknowledge your growth outwardly, but their perception of you is still heavily influenced by the past. They remember who you were, and it's much harder for them to accept the new you, especially when you're showing them up by not losing your cool like they do. When you don't react to their provocations, when you walk away from fights, when you refuse to engage in their arguments, you're essentially showing them that self-control is possible. And that makes them angry because they can't do it themselves. They want you to fail, to lose your temper, to prove that you're just like them. When you don't, it exposes their own weakness. Keep doing what you're doing. Your self-control is a tremendous achievement, and the fact that others are getting upset about it is actually proof that you're doing something right. Continue to work on yourself, and don't let their anger or their attempts to provoke you pull you down to their level. In the end, they're going to see your consistency, and either they'll respect you for it, or they'll leave you alone. Either way, you're better off.
