Psycho or Angry...where is the line?

Well, it really depends on how bad the person is acting. If the person will no longer listen to reason then you have a serious problem. I'd say if a person you care about rejects your sympathy, advice or opinions, then that's when you draw the line... and of course you know the situation is ridiculous if they're seriously acting immature, you probably know enough examples for me not to list them. You should be able to tell.

. Being angry is a temporary state. You get worked up, you explode, you calm done. Psycho is a constant state of mind which lacks the buildup and calming period.

As for your example, if they camp outside your door for hours or days and plead, beg, scream, yell then I'd definitely file in them in the Do-Not-Call-List.

I think I get what you're saying. It's one thing to show up all of a sudden and want to talk, it's another to be pounding on the door. Once our heart's involved, there's always the chance of saying or doing something stupid. But I think the line is an easy one to know; you feel it.

Personally I think it's hard to say that you act aggressively toward someone because you love them. I agree with 3Hundred - there's a gap between these two and anger can be expressed in lots of different ways. Like Fastball sang, "There's always more than one way to say exactly what you mean to say." If he loves you, then he has to change now. If not, then I say he's unstable and you should leave him.

It becomes a psycho behavior, the first time you witness it, It shouldn't be that easy to get upset by someone you love, and In a guy if he shows up crying and yelling in such, than you have a a Crazy boyfriend.. I can't think Of any reason to show up, to my girlfriend crying/yelling. I deal with these things totally different as do many people I know. and if you even had to ask this question Obviously there is something Wrong!

I disagree that the lines between psycho and angry are close. You can be angry at someone and not talk to them for a week or even longer, but that doesn't mean that you go mad and set their house on fire. There is a VERY clear distinction between those two. I don't know what makes you think that those two could even be close, could it be that you always got the short end of the stick and were not so lucky with your relationships? If that's the case, I suggest you do some drastic changes in your life.

I'd say once they lay a hand on you, it would be psychodic. If they are just mad, you could usually tell! If they are psycho, they'll just go off on you for no reasoning what so ever! That's how I feel about it!

Crazy: continuing to ignore facts that have been clearly demonstrated. Following you and demanding answers to questions you've already answered...50 times. Following you to work past the point of reason (ie, behind a counter, or even to your desk if he has been repeatedly asked to leave, and finally a supervisor has to remove him). Having a complete meltdown about things that don't go perfectly his way. Drastic personality changes around other people to gain sympathy and make you look like the bad person. Once you start having to consider a restraining order. And once they've made you afraid of them, by threats or actions, it is a BAD THING. I lived in fear of this guy for months and never did anything about it because I felt that I was overreacting. In retrospect, and according to my counselor, I should've just gotten the restraining order.

Somewhat less common, that falls only under crazy (and not really upset), is lying to the FAA about serious medical conditions that typically prevent you from getting a pilot's license. That seriously should have been a hint that I should have paid attention to.
