Letting go is much harder than it seems

I never thought it would be easy, but guess I never thought it would be so hard.
It's very difficult to explain and I'm not even going to try to put my feelings into words because I know it's gonna sound pathetic, won't make sense and will not adequately reflect what it should.
But I'll give you something easier to see and understand, which is very real, as an example of it all.
My suitcase!
I initially was planning to bring a suitcase I had at home and a relatively large carry on - after all it's things I need for the next 6 months or so.
Then I started realizing I didn't really NEED anything, and I should be practical and bring along with me as little as possible.
So I picked a small backpack as my carry on and bought a convertible backpack to be my suitcase. For those of you who have backpacked before, mind you this is actually a big backpack, fits 80 liters.
As I started emptying my closets and boxing things to go into storage, I separated the things I would initially like to bring along on the trip. At this point I already knew that as little as I managed to separate I would have to cut it down and re-pack a few more times before taking off.
And I did.
But my mistake was that I never really tried fitting everything into the bags until the very last minute. And on the morning of my flight, guess what?
I had too much.
In the rush of the moment, I panick packed. I opened up another box to go into storage in which I just kept throwing things randomly, while I secretely prayed that I wouldn't think of those items at some point in the trip and regret not having brought it along...
Of course, I still didn't manage to fit everything and a small foldable bag that was supposed to be only used towards the end of the trip as I started accumulating new stuff I would get along the way, left the Netherlands full...
I looked like chaos in person when I got to the airport.
But checked in the backpack and the yoga mat (forgot to mention that earlier) and still had my purse, a backpack and another bag with me as carry on.
Arriving in Dubai, after I picked up my checked in luggage I felt like one of those bag carrying donkeys. And trust me it was pretty heavy to carry all those bags around.
I drove to the hotel determined to unpack and repack everything, leaving a good chunk of it behind.
Tomorrow I leave again to India. Will once again have to do the bag carrying saga.
I unpacked and repacked.
Guess how many things I managed to get rid of?
A small mirror and a little free sample bottle of eye cream...
This time, there was no panick packing. I just really NEED everything.

So you're thinking, what does she have in her bags that is so damn important?
The answer is not a lot actually. And I do know I don't need half of the stuff. But I just cannot bring myself to let it go.
Not yet at least.
So long story short:
I decided to be patient, and give myself some time and space to get used to this "new lifestyle".
Eventually I'll learn to let go. Either by overcoming the psychological barrier. Or by being physically exhausted of carrying so much weight around.
