Amazing story!
Two years ago I also moved to Bulgaria from the Netherlands, it has been a big step and I learned so many things about myself, life, responsibilities and relationships.
You might be leaving your old relationships behind, they are always welcome to come around and they would be bad friends if you are not welcome anymore whenever you get back.
New relationships can always be made when you move to a new location.
I started going to yoga studios literally the first week I was here and it has definitely been the best decision. The doors that open up through yogis, they are the coolest people :)
I hope you keep doing exceptionally well in the GB. Visit some stone circles when you get the chance, their energy is magical.
