We all need to find a place to be called my sanctuary.  When you have to be strong for those around you, remember where you received your strength in the first place.
And if you forgot where that place was or it no longer holds any meaning for you, try and find a new one. Finding our inner ground, our inner peace will give you the stability that you need to be strong. Find your place of peace and you will find your way.
Side note, I am not talking religion. I am talking with my heart. My strength is not your strength, we must find our own acceptance.
