I got the quote below from another blog... I think it says a lot. Firstly about the numbing a person part.. I can testify to that. For me, when I was in love, nothing else mattered. Blinded by my own selfishness...

I think it is a blessing that you feel lonely. why do I say that? Those who can feel the pain of loneliness are gifted with the ability to understand those who don't feel loved out there. You can reach out your hand and do so with the greatest intentions and understanding, because you know how it feels. Being satisfied, and not feeling lonely, does nothing but numb a person with a paralyzing complacency.
Theres another example of human nature for you.

Maybe this really was necessary for me to grow up and mature. So many people are looking for God and I've found Him... How fortunate am I? One relationship for another... But this one lasts forever... I guess I'm better off.

Dear Lord, I want to come back to the basics again... I've been inadvertently distracted by people and things that I have to do. I've let myself be surrounded with all this to drown out the lonliness... Lord, help me remember that all I need is You. I'm nothing without You. Amen.
