How do i stop this

How do I stop being so heartless I mean dang I met some mean people in my life. But jeez I could steal someone wife. Make her have a baby. and just forget about her and the baby. how do I try to be nicer

Think what you say before you say it! Or just try to find sympathy, open your heart to people!

start putting yourself in other peoples shoes when you realize your being mean to them.

I dont even think I got a heart lol.

think about weather or not you would want this done to you and if the answer is no then dont do it. turn things around.

even if it is done to me ill just walk away from it

I thiink it should come natural. people that really have a heart dont have to try. when im nice to people its because I genuiunely wanna be. im not saying your a bad person, im just saying think about what you do before you do it, a lot of things effect peoples lives. and I believe karma strongly so I know w/e I or someone else does is gonna come back around and bite cha in the a$$ fo sure=]

IF you are serious about change, the only way will be with therapy, and lots of it.
You are basically describing a borderline sociopath.
Good Luck!!
