Hiya,
So, adjusting at first was...hard. I think it's because the first two days I was here I didn't know ANYONE, didn't have a cell phone and had no internet! So I felt kind of trapped. But once I went into town, got a mobile, upgraded my living situation to where I had internet, things got a lot better. Also, I met my other classmates I think the fourth day I was here during orientation, so finally I was able to make friends.
After I got over myself I really enjoyed my first year here. Ireland has probably one of the most beautiful countrysides in the world. Everything is so green, there are sheep EVERYWHERE and cattle grazing on pasture to be seen next to every highway.
This city of Dublin itself is really young. Literally. 50% of the population is 25 years old and under. It has a really great vibe and the night life here is insane. There are so many pubs, clubs, restaurants, cafes....You can't go anywhere being hungry or thirsty, Dublin definitely has a thriving food industry.
Does this help? Let me know if you need me to be more specific...
