Why is Chess so rage inducing sometimes?

Just look at my last chain of games and you'll understand why i want to throw my monitor into the trash can... While we're here... what is the most rage inducing moment you've had in this game? An annoying opponent? Losing on time while vastly ahead on material? 

Because people are immature.

Probably when I misclicked sometimes when I had "drag or click" enabled by default, seriously why is that a thing?

The time I got annoyed the most was that I got accused of cheating when I blundered my queen. Like, are they not using their brain?

I don't think being mature affects your anger, The real thing that affects your anger is your ability to calm down.

And we can agree to disagree. But if playing chess online is going to induce rage, not anger, not annoyance, not bitterness, but rage. You need some professional help. And honestly "rage" is just another online thing.

Look up the definition of rage: violent and uncontrolled anger. If online chess brings that out in you then you need help.

because it's not your teammates, it's you

You don't really need professional help unless you destroy your desk all the time or harm someone, You probably can meditate or something to get rid of it, Help yourself, You do not have to buy anger management therapy or talk to a professional in that case, There are affordable ways to decrease your Rage or Anger or whatever if you want something a more cheaper.
