stop being so critical of everything

I have seen the reactions of others to this flaw o’ mine. They clam up, they back off, they reserve the full expression of their thoughts and feelings.

I don’t want to cause that anymore.

im still having problems with this. I hate that I am overly critical of everything. I have tried to stop. And when I feel myself about to say something to someone, usually I stop myself. But then it eats me up inside and I feel like I should have said something. I dont know what to do about this one!
