One of the mums here on TSR and I imagine its a big transition uni to work life, and your travelling as well for 6 months.
You will get this with what ever job you do. Your only allowed X amount of days holiday entitlement, and you have bills to pay so whether its working at a shop, office, or a watersports training centre, or go ape, its still work at the end of the day.
Meditation is amazing, I do it quite often. You do need also something to focus on. For me, its my holidays and I never finish a holiday not having the next one booked. I also did Tai chi classes and Zumba which helped me meet other people and also had a nice routine going doing things I liked.
Regarding your job you are in now. Definitely give it some time. You can either end up hating it which means you can look for a different job in something you might like, or you end up liking your job after all and it was just the transition part that was the problem. Either way this will look good on your CV if you have a working history. But yeah definitely do some things to give you structure whether thats night classes, gym, meeting with friends, a weekend away in a cheap hostel, putting that deposit on that next holiday
