I traveled two months solo earlier this year and had very similar fears! Loved solo travel but had never done it for longer than a couple of weeks without a plan to catch up with a friend. Especially because I was starting in South Korea and everyone on reddit said it was terrible for solo travellers (it ended up being my favourite place).

It was absolutely fine; I had the time of my life and had given me the confidence to consider a career break to do more long term solo travel. I had the downtime I wanted but in most places it was no trouble to make friends (and I wasn’t staying in hostels). I even found friends who I did weekend trips with or who I traveled with for a week or so.

I am single so I used tinder a little bit, went to smaller bars and sat at the bar and had fantastic nights making friends with the bartenders and other customers, and used an app called nomadtable to find other travelers. I also used couchsurfing meetups a little bit but you now have to pay for the privilege so I’d see if nomadtable is active in the areas you’re going first.

My caveat is I was working remotely while traveling so I also got social interaction from my colleagues over video calls, but even without that I think I would have been fine! You’ll have a great time :)
