@lmika I think it's hard to feel enthusiastic about travelling when you're feeling rotten with an illness and struggling with a language barrier and so forth. And I think as I've got older I've had more and more of the excitement I used to feel intermingle with anxiety when I travel. But it's all OK. Try not to put too much pressure on yourself, and take things as they come. If you'd feel really relieved to come home early, I think it's OK to do that. On the other hand, if you'd feel a bit of lingering guilt or something, then maybe don't. In any case, I hope you feel less miserable soon.
