What is going on??

This morning I turn on the tv and hear this... "A teenage gunman who launched a shooting spree in a school in southern Germany killed 15 people before being shot dead by police." Then a few minutes later the headlines were this....A slaying spree spread across two southern Alabama towns left 10 people dead Tuesday. The gunman then took his own life....I heard that a good friend of mine that lives in New York had a scare of his own when his wife who works at a school in a not so good area text him to say there were shots fired...I'm sitting here thinking what on earth is going on??? Has everyone lost their damn mind!?!? According to the reports Ive heard from each of these incidents no one knows what caused the shooters to go on their rampage. I just don't get it why go and kill innocent people??? And then to top it off kill yourself???? What is going on with people?? Life is rough but it certainly isn't THAT rough no matter what is happening in a persons life there is always a solution...they just need to look for it...reach out to those around. Take advantage of the help that's there for people. Don't just decide that they can't take it anymore and go on some rampage and start killing people that are trying to live their life. This truly just frustrates me!! And makes me feel like I need to live in fear myself not knowing who will be the next one to lose their mind, and if I or my loved ones will be the innocent ones that happen to be at the wrong place at the wrong time. That's NOT how life should be!!!! And this craziness needs to stop!!
