A little more info might help the answers. What country are you going to? Do you speak the language? Where will you be living? Is the program a “ your university in Paris” program or is it one where you study abroad at a foreign school? Are other students from your university doing it too?
I think if you thought you could do it before you can probably do it now. Your anxiety is kicking in now and clouding your judgement but if you thought it was something that was right for you before, your judgement unclouded by anxiety is probably the judgement you should listen to.
What year are you in school? Junior? If you’re a sophomore you might be able to put it off due to COVID and try again next year, but if you’re a junior you don’t usually have an opportunity for study abroad as a senior.
I think some strategies may help you. First figuring out how you can make friends is key. If other students from your college are going the same place talk to them now if you can. Reach out to your international studies office and ask them for ideas. They may be able to put you in touch with other students who are also going. See if there is a group online for the program. Also talk to students who have been before. Here again the office you are coordinating through maybe able to put you in touch. Or you could just google something like “my semester abroad in Paris blog” and read someone else’s account.
Anxiety is often triggered by fear of the unknown — not knowing what something is going to be like. Do all you can to research your program. Go on Google Streetview and virtually walk around the area. Talk to people who have done it if you can or read some blogs. Watch YouTube videos. Obviously other people’s experience won’t be the same as yours but it can help erase some of that fear of the unknown.
Ok, here’s a weird suggestion, but see if there’s an episode of “Somebody Feed Phil” that is set where you will be going. Don’t know if you’ve ever watched that show but Phil is such a positive, lovable goof that our vegetarian family doesn’t even mind watching him rave about how good the meat tastes wherever he is.
I did not study abroad when I was in college and it is now a big regret of mine. I have a friend who did a year abroad in Edinburgh and she made great friends who she has been back to see and who have come over to the US to see her.
Hope this helps. Anxiety sucks. I get anxious myself and both my kids have clinically diagnosed anxiety so I understand. I think one of my kids does want to do study abroad (she’s a high school senior now) though and I think she will have a great time and I bet you will too.
