My ( F21) bf (M25) is going to travel from Romania to Turkey by car for his summer holiday with his parents. I couldn't join because I have a job and my vacation days ran out. Why does the thought of him traveling by car makes me feel anxious? I am aware that this is all in my head, but I can't calm down. He's going to stay there for 2 weeks. I just want him back home safe and sound already.
