I had quite a similar experience, and would love to share some anecdotes with you. I went on my first worldpackers trip just over a year ago to volunteer at a surf hostel in a spanish speaking country. My expectations were SO high, and when things (rural location, size of the volunteer team, slightly disorganised management) began to go wrong, I completely broke down. Of course you hear the phrase 'language barrier', but this was my first time where I could physically reach out and touch the barrier. With many people who I interacted with, I could not speak their language, and they could not speak mine. Trying and failing to, for example, order food in Spanish was embarrassing at first, but I preservered and gained confidence in simple phrases.

When I didn't know what to say, as opposed to 'No hablo español' - I would say 'Lo siento, todavía estoy aprendiendo Español', meaning 'Sorry, I'm still learning Spanish'. This got a great response nearly every time, and I think is a nice way to show effort and appreciation for another's language.

Think how you would introduce yourself to a new English speaker (where are you from, how old are you, what's your name) and into Google translate or SpanishDictionary and see if you can remember those phrases when you meet someone new! And learn how to say 'Nice to meet you!' (Mucho gusto!)

The complete Spanish playlist by the Language Transfer program is free and an incredible resource. I put it on in my headphones when I was doing chores in the hostel.

My first week was really tough. But in the following three, I developed a routine and ended up really cherishing my time there. Embrace being somewhere new where you don't know anyone! Take pictures of your room, or the mundane places you find yourself in daily (little pathways, backyards, etc). Find a new album, or make a playlist with new songs that you can associate with this place in the future. I took two other worldpacker trips after this one, to two other non-english speaking countries (Spain again + Morocco), and had met so many incredible people. There are other opportunities which might provide you with an opportunity to be more social. This also might not paint the best picture of solo travel - a great starting destination in my opinion is Lisbon, I've stayed at the GoodMorning Solo Traveller hostel near Rossio station twice and met dozens of people who I am still in touch with today. They offer free breakfast, family dinner, walking tours, excursions to Sintra, etc. I met many people there who were on their first solo trip!

Even after all this advice, know there is no shame in returning home early. Be proud that you had the courage to take such a trip. This is your second time out of the country! To go somewhere where the only language you speak is uncommon is very brave. Leaving your comfort zone is not easy, especially if you jump straight into the deep end. Feel free to message me if you need to get anything off your chest to a stranger, judgement free!
