Help me to stop thinking horrible, mean ,negative thoughts about others

[Negativity]

I cant seem to stop. Its hard to explain, but I am always suspicious of peoples motives, think they are self serving and selfish, and cannot believe people do things just because they are nice things to do.

I dont think it about everyone I deal with in life, just some people in my family who have disappointed me in my dealings with them. Its almost like I've black marked them and cant shift my thinking on to become postive about them

I like to be proved right about a situation , I secon guess peoples motives. For examplpe, my BIL and SIl are planning to extend their house quite considerably to make a granny anexe for her parents in prepartion for their old age.

A normal perosn would think' oh what a nice selfless thing to do'

I think 'Oh thats a nice cheap way to make your house bigger, she always gets what she wants, why cant they pay for it themselves blah blah blah' I base these thoughts on previous experiences with my bil and sil. But the bottom line is, Its none of my bloody business! I'm aware it sounds like I think I'm perfect in every way too, casting judgement on others.

How can I stop thinking the worst about people?

Try some creative writing exercises:
Write about the situation from your point of view and from theirs. That might help get some perspective.
Also, try having a look at what you've written after a few days.

I don't think you're abnormal, though.
Everyone goes through phases of feeling mean spirited about other people. At least you're aware that that's what you're doing.

Thats a good idea plump

I know its normal to feel like this but I hate myself for the superior attitude it brings too.
