Hello Mike,
I never bought anything from you (though had I had the money, I did fall in love with the lavender Pineapple Sunday, what a beauty!).
I'm new to the uke community, and to ukulele, but which ever site I went on, you appeared! Not only was your ebay store cited, but you were (and still are) described as the best seller in the uke community. Again, had I had the money, I would have bought the ukulele with no doubts, no questions as your reputation precedes you.
Don't worry about a few negative feedbacks. As a regular ebay shopper, I can assure you that with 18 000 positive feedbacks, you shouldn't fret it. You know when looking at feedbacks, that you will always have some grumpy person stating they aren't happy, but some people are NEVER satisfied no matter what you do. They lead a sorry life.
Now, you need to focus on yourself, on the positive and on getting better! It's time to be selfish and egocentric. Rely on your loved ones and let go of anything dragging you down.
Hoping you'll fell better soon!
