Advice and tips for living alone in a foreign country? 🧳

Hello, So I'll be moving to Europe in a few months for an internship(3 years. Can be extended). I'll be paid and provided accommodation. But it's my first time travelling to a foreign country and I have no idea about anything at all.

1• What will you recommend for me to pack?

2• Something you wish you knew when moving to a foreign country all by yourself?

3• How do I feel safe living alone?

4• Safety measures while travelling/walking all by myself?

5• What are the social/work/diner etiquettes in Europe?

6• What outfits are appropriate for work(and also outside of work)? What to avoid?

7• Any advice/tips are welcome!!

Thank youu!🌷
