Hi Ellie!
I'm new too, and I hope you find this forum and friendly and helpful as I have already!
I just wanted to offer you a bit of support and encouragement...I went to college in London, and graduated in 2001. I ended up living there for 4 years total. It was the most wonderful experience of my life. (Plus, I managed to snag myself a man, and am returning to get married in Feb!) Living there day to day is such a different experience from visiting as a tourist...you will experience the wonderful culture in a very deep and personal way, and it really will broaden your horizons. I wish every young person had the same opportunity!
I, too, left behind a horse, and sadly had to sell him before I went. It was a very difficult decision, but in the end, I was glad for it. He found a wonderful loving home, and I was able to come back to the States after school without feeling tied down to anything...it was a great feeling, like I could go anywhere! I made the decision not to visit him, as it would have been too traumatic for both of us, but his new family still write emails to me and send photos every once in awhile, and I know in my heart he's happy. These are all things to think about when making your difficult decision.
I'm in the process now of applying to bring my cockatiel over ot the UK with me. With the new PETS travel scheme, it's easier than ever to bring your furry friends into the UK, and they don't have to go through that horrible quarantine like they used to! I encourage you to start looking into this! You have to start planning well in advance (over 6 months for dogs, I think), but your doggy will surely enjoy sharing your new life with you!
Welcome again, and keep us updated on your plans!
