An Overreacting Reaction 
We all do it, hell I have done it a few times in my life...more than I wish. Yes, overreacting is what I am speaking of...something in which we all do. Or you could call it; jumping to conclusions. 
Decisions others make, comments others make, or actions others do cause us to get into this mode of being VERY efficient when it comes to jumping to conclusions. What causes this? I have wondered about such a thing since I had the ability to really elaborate on things. 
Is there a "cure" for such an action? Eh, not necessarily. There is and there is not. 
Sometimes we cannot really control how our emotions or feelings react to certain situations or predicaments, what matters most is understanding you overreacted. Sure we always have the ability to prevent ourselves from getting into these types of situations...but like I said earlier it is a matter of understanding why we reacted this way, and adjusting/fixing it so it does not happen again. 
To really get into this, I must say I have not truly figured out what really causes us to act in such a manner. Is it that the average person thinks negatively most of the time? Or is it that we always expect THE BEST POSSIBLE scenario at all times? I would go so far as to say it is a little bit of both. Expecting the best possible scenario usually ends up bad when you are hit with ANYTHING less than what we expected. Now am I saying that we should expect the WORST case scenario? No, not necessarily, maybe try to mix in a little bit of both...or better yet, DO NOT expect anything--relax and let things go the way they go. 
If you think about the best and worst case scenario, understand each one, then just sit back and RELAX you will prevent yourself from overreacting and making a complete fool out of yourself...trust me, it works...but I do not listen to my own advice as much as I should haha. Seriously though, we could easily save ourselves a lot of trouble, pain, and mental anguish if we just relax and understand the possibilities. Expecting situations or answers to go in one way or the other always ends up tragic...well, maybe not tragic, but not so good will work. 
Sure, it may seem easier said that done, but nothing great is easy to do. You will feel better about yourself and you will save yourself (and the individual talking to you) the annoyance of overreacting. Another thing you can do as well, with short answers that lead to jumping to conclusions--ask questions. Just ask them; "what do you mean?" Not; OH MY GOD WHAT!? NO, I DON'T UNDERSTAND AHHHHH, BLAH BLAH AHHHHH!!!!! No no...that will just NOT do. Relax, chill out, breathe, and ask questions...understand the decision in full. Know the details, know the reasons, know why you should NOT jump to conclusions. 
I love you all.
