Tough it out and then see how you feel. First few days in any job are shite, shit, even first few weeks/months. Everything is new, unfamiliar people and location and yet to see a payment into your bank account. I remember starting in courts and hating everything. The journey to Dublin, the tram to courts infested with heroin addicts, the mindless filing of applications/orders (far removed from the high brow shit you learn in uni), the clothes I had to wear... everything was shit and strange.
Soon you grow into it, find friends, become familiar with the building and location etc. If you still hate it then reconsider your circumstances.
