YMMV is something I’ve heard usually in connection with results/side effects of medication.
Examples; How long did it take for it to work for you? What side effects did you have?
And we are told, your mileage may vary. Simply put, all of us react differently but don’t be afraid to try it. It may be the key you have been looking for…

Isn’t it true of many things, though? Our paths of healing are our own. What worked for others may not work for us. What worked for us may not do a darn thing for someone else.
Again--we walk solitary paths, but they are parallel to others. We are not alone in our travels, period. A stumble? Hands reach out to steady us. Detours? Quite all right…no one can sustain walking the straight and narrow all the time. Who wants to do that anyway? Be grimfaced and stoic in our determination to rid ourselves of emotional pain and loneliness Some of those detours are the best things that can happen to us…strips us of things that were not working for us, forcing us to look for other ways, and perhaps people who will give us encouragement of a different kind.

YMMV is also another way of very clearly saying;
Comparisons are useless and somewhat dangerous to us. Someone will always be ahead of us, someone will always be behind us.
And
We are judging someone’s outward appearance when in reality they may be hurting as badly as we are…when we look at them, we feel that they have everything together. They may be doing the exact same thing…
So we shy away from each other, thinking we are somehow less. In doing so, we are depriving ourselves of the lessons each of us have to offer one another.

Tread lightly, though.
We cannot get so entangled with another person’s pain that we forget to take care of ourselves.
Caretaking is a trait that is extremely well developed in most of us. It is also one of the most difficult to let go of…caretaking can make us feel needed, but it can also keep us from paying attention to our own needs.
Balancing it?
Foreign words to many of us. It’s either/or, there is no separation of taking care of ourselves and doing it for others.
Others will always come first if we allow it.
We can help, but we should not stand in the way of someone taking responsibility for themselves.
No one should stand in our way, either.

One last thought;
We are in the right place at the right time for the right reasons that may never be revealed to us…don’t waste time trying to figure it out. Most likely the knowledge of it may be the byproduct of putting one foot in front of the other, and not looking back.

In Peace
