Something really bad must have happened to you...I'm sorry for that....only thing you can do is change your perception of whatever it was.....Because the perception you have now is not correct.....
Many times in my life I've had people suggest things to me and I have shined it on....only to later find out they were entirely correct....Now I pay more attention...or at least try to....
There's a reason I happened across TA .....maybe it was for your benefit?
