I remember feeling lonely when I hired a cottage in the Lakes just for me, in my mid twenties. The days were alright, but every night I went to bed early with a book. Didn't seem much point in staying up, and I don't like going in pubs on my own. Fast forward, I am now more confident and happy to be on my own, but I don't camp because I like the interaction with other hostelers, or with the owners of the B & B I am staying at.
My house/cat sitter sends me text updates about what is going on at home, and sometimes phones, this helps. Maybe get someone to keep in touch with you, family, friends.
