But not everyone feels that way and that is the problem with telling others that statement standalone. If it works for you, in your own mindset that is fabulous, fantastic. It still may not be the right thing to hear for all people.
There are bad things that happened in my life that just suck. There is no reason. There never will be. Even if, sometimes, I can see something positive came out of it, that wasn’t “the reason” the bad thing happened. The bad thing still sucks. It also implies some sort of higher power or pre-ordained plan, looking at it from many angles.
That said, I think saying to someone “For me, I have found everything has happened for a reason in my life” is not putting responsibility on the sad/hurt party but explaining your experience. That seems less of an issue…
