You should decide if the current life is something you see yourself doing till your like 55. Add in a wife and kids in Ireland. Do you like it? I would go back if certain things were different and I had nobody here who I wanted to stay back for. I miss my family and friends.
At some point you have to decide if the mental load of earning bread outweighs the joy of family. You should take a long vacation and self reflect. You don't have a relationship with Ireland yet, you can move closer to your country. I wish I could've done it.
I have to train a branch manager's daughter from Monday. She has no business coming in here apart from her dad. But oh well, Neither did I when I joined. I haven't even been here for a year. Why do I gotta train her and not the other more experienced ladies? Does my manager think I'm just sitting around anyways?
