Feeling a bit stuck, looking for advice on where to go/ what to do next

Hi all, 32 year old solo traveller here. I’m about 2 months into a 4 month trip. So far I’ve done a couple of stops in the US, then Puerto Rico, Iceland, Spain and now I’m in Portugal, where I’ve done a surf camp in Ericeria, 2 nights in Lisbon and I’m on my way to Porto for 3 nights.

So, I’m feeling a bit exhausted to be honest and like I’m on the go a lot! I have about 4 weeks from July 10th where I planned to travel through Italy and a bit of Germany – but there’s something holding me back from booking anything, and I’m not sure what to do. Should I just get on with, stick with my initial plan – or change track? Maybe pick a city to base myself in for a month and do short trips from there? If so, what city? As you can probably tell I’m a bit all over the place! So any and all suggestions welcome :)

Edit: I just found which was really helpful . I think I’m experiencing a bit of burnout, but I’ve felt like this for a little while now. Will try to use my time in Porto to rest and reassess in a few days.
